fruits Questions in English

(D) composite or multiple fruit is a group of fruitlets that develop from the entire inflorescence rather than a single flower.
Based on the list provided:
$1$. Fig ($Syconus$ type)
$2$. Pineapple ($Sorosis$ type)
$3$. Mulberry ($Sorosis$ type)
Walnut,poppy,radish,apple,and tomato are not composite fruits.
Therefore,there are $3$ plants in the list that have composite fruits.

(A) : Drupe is a fleshy fruit that develops from either one or several fused carpels and contains one or many seeds. The seeds are enclosed by the hard protective endocarp (pericarp) of the fruit,$e.g.$,mango. In mango,the pericarp is well differentiated into an outer thin epicarp,a middle fleshy edible mesocarp,and an inner stony hard endocarp.

(B) : Syconus fruit develops from a hypanthodium inflorescence,$e.g.$,$Ficus$.
Hypanthodium is a box-like inflorescence where the box is formed by the fleshy receptacle.
It opens to the exterior by a single pore called ostiole.
The hollow,pear-shaped fleshy receptacle encloses a number of minute male and female flowers; it becomes fleshy and forms the fruit.

(C) $Syconus$ develops from the $Hypanthodium$ type of inflorescence.
The flask-shaped fleshy receptacle encloses female flowers, which produce small $Achene$-like fruitlets, and it has a small pore protected by scale leaves.
Example: $Syconus$ of $Fig$ $(Ficus \text{ } carica)$.

(D) : Cypsella is a dry,one-chambered,one-seeded fruit developing from an inferior,bicarpellary syncarpous ovary,$e.g.$,sunflower,marigold,cosmos,etc.
Caryopsis or grain is a small,dry,one-seeded fruit developing from a superior monocarpellary ovary,where the pericarp is fused with the seed coat,$e.g.$,rice,wheat,maize,etc.
Cremocarp is a bilocular,two-seeded fruit developing from an inferior bicarpellary ovary. It is the characteristic fruit of the family Apiaceae (Umbelliferae),$e.g.$,coriander,cumin,etc.
Berry or bacca develops from a mono- or multicarpellary superior or inferior syncarpous ovary with axile or parietal placentation,$e.g.$,tomato,banana,brinjal,guava,grapes,etc.

(C) : In pomegranate,the fruit is chambered and develops from an inferior,multilocular,syncarpous ovary. The seeds are characterized by a succulent (fleshy) testa,which is the edible part of the seed.

(D) : Pineapple is a $Sorosis$ type of fruit that develops from a spike or spadix inflorescence. In this type of inflorescence,the flowers fuse by their succulent tepals,and the axis bearing the flowers becomes fleshy or woody,thus forming a compact mass. These are known as composite or multiple fruits. In pineapple,the fleshy axis,bracts,fused perianth,and pericarp are edible.

(A) The correct answer is $A$. In $Litchi$,the edible part is the fleshy $aril$.
An $aril$ is a specialized outgrowth that develops from the base of the ovule and covers the seed. It is a fleshy,succulent structure that is sweet and edible.
In $Litchi$,the pericarp (fruit wall) is leathery,while the $aril$ surrounds the seed and serves as the edible portion. Other examples of plants with an $aril$ include $Asphodelus$,$Trianthema$,and $Ulmus$.

(B) An aggregate fruit,also known as an etaerio,is a collection of simple fruitlets that develop from the free ovaries (apocarpous condition) of a single flower. In this condition,the gynoecium consists of multiple carpels that are not fused together,allowing each carpel to develop into an individual fruitlet.

(A) The provided diagram represents a cross-section of a fruit (specifically a maize grain or similar monocot fruit).
In such fruits,the inner structure represents the $X-$ seed,which contains the embryo and endosperm.
The outer protective layer surrounding the seed is the $Y-$ pericarp,which is fused with the seed coat in grains.
Therefore,$X$ is the seed and $Y$ is the pericarp.

(B) Mango is scientifically classified as a $Drupe$ fruit.
In a $Drupe$,the fruit develops from a monocarpellary superior ovary and is one-seeded.
It consists of a thin epicarp,a fleshy edible mesocarp,and a hard stony endocarp that encloses the seed.
Therefore,the correct classification for a mango is a $Drupe$.

(C) In coconut,which is a drupe,the fruit develops from a monocarpellary superior ovary and is one-seeded.
In a drupe,the pericarp is well-differentiated into three layers:
$1$. The outer thin epicarp (skin).
$2$. The middle fibrous mesocarp.
$3$. The inner stony hard endocarp.
Therefore,the mesocarp of a coconut is fibrous.

(C) The figure shows a mango fruit,which is a type of fruit known as a drupe.
In a drupe,the pericarp is well-differentiated into an outer thin epicarp,a middle fleshy edible mesocarp,and an inner stony hard endocarp.
The label $X$ points to the hard,stony inner layer of the pericarp,which is the endocarp.

(C) In mango,the fruit is a drupe. The pericarp is well-differentiated into three distinct layers:
$1$. Epicarp: The thin,outermost skin.
$2$. Mesocarp: The fleshy,edible middle part.
$3$. Endocarp: The hard,stony inner layer that encloses the seed.
Therefore,there are $3$ layers of pericarp in a mango.

(A) The fruit of groundnut $(Arachis hypogaea)$ is botanically classified as a $Legume$ (or $Pod$).
Although it develops underground due to geocarpy, it retains the structural characteristics of a legume, which is a dry, dehiscent fruit derived from a single carpel that splits along two sutures.

(B) In mango (Mangifera indica),the fruit is a drupe.
It develops from a superior ovary and is one-seeded.
The fruit wall is differentiated into three layers: the outer thin epicarp,the middle fleshy edible mesocarp,and the inner stony hard endocarp.
Therefore,the edible part of the mango is the mesocarp.

(B) The coconut fruit is a drupe. In a drupe,the pericarp is well-differentiated into an outer thin epicarp,a middle fleshy or fibrous mesocarp,and an inner stony endocarp. In coconut,the mesocarp is fibrous and is the source of coir.

(B) banana is a berry fruit. In a banana,the outer thick skin is the epicarp. The edible portion consists of the fleshy mesocarp and the less developed endocarp,which surrounds the seeds (though seeds are often vestigial in commercial varieties). Therefore,the correct answer is $B$.

(B) geocarpic fruit is a fruit that develops underground.
In the case of groundnut ($Arachis$ $hypogaea$),after fertilization,the flower stalk (gynophore) elongates and grows downwards into the soil,pushing the developing ovary into the ground where the fruit matures.
Therefore,groundnut is known as a geocarpic fruit.

(A) In mango $(Mangifera \text{ } indica)$, the fruit is a drupe.
It develops from a monocarpellary superior ovary and is one-seeded.
The fruit wall is differentiated into three layers:
$1$. The outer thin epicarp (skin).
$2$. The middle fleshy, edible mesocarp.
$3$. The inner stony hard endocarp.
Therefore, the edible part of the mango is the mesocarp.

(D) In citrus fruits like lemon,the edible part consists of juicy,hair-like structures known as juice sacs. These juice sacs are unicellular outgrowths that develop from the inner epidermis of the carpel,which corresponds to the endocarp of the fruit. Therefore,the correct answer is the endocarp.

(B) Pineapple $(Ananas)$ is a type of multiple fruit or composite fruit.
Multiple fruits develop from an entire inflorescence rather than a single flower.
In the case of pineapple,the flowers are borne on a common axis (spadix-like inflorescence).
These flowers fuse together along with the floral parts to form the composite fruit known as a sorosis.

(B) The fruit described is a $Cypsela$.
$1$. It is a dry,indehiscent fruit.
$2$. It is single-seeded.
$3$. It develops from a monocarpellary (or bicarpellary),syncarpous,and inferior ovary.
$4$. This type of fruit is characteristic of the family $Asteraceae$ (e.g.,sunflower,$Tridax$).

(A) The inflorescence in $Ficus$ is known as a $Hypanthodium$.
In this type of inflorescence,the receptacle becomes fleshy and forms a cup-like structure that encloses the flowers.
The flowers are unisexual and are borne on the inner wall of this receptacle.
After fertilization,the female flowers develop into small,dry,one-seeded fruits known as $Achenes$.
Therefore,the fleshy receptacle of the fig encloses a number of $Achenes$.

(A) The fruit described is a $Balausta$,which is characteristic of the pomegranate ($Punica$ $granatum$).
$1$. It develops from an inferior ovary.
$2$. The fruit is fleshy and indehiscent with a tough rind.
$3$. The interior is divided into many chambers by septa (partitions),and the seeds are attached to these septa.

(B) $Syconus$ is a type of composite fruit that develops from a $hypanthodium$ inflorescence.
In this type of inflorescence,the receptacle becomes fleshy and forms a cup-like structure,enclosing numerous small flowers.
Examples include $Ficus$ species like the fig $(Ficus \text{ carica})$ and banyan $(Ficus \text{ benghalensis})$.

(D) drupe is a type of fleshy fruit that develops from a monocarpellary superior ovary.
In a drupe, the pericarp is well-differentiated into an outer thin epicarp, a middle fleshy mesocarp, and an inner stony hard endocarp.
Mango $(Mangifera \text{ } indica)$ is a classic example of a drupe fruit.
Therefore, the correct option is $D$.

(D) composite fruit (or multiple fruit) is a fruit formed from an entire inflorescence rather than a single flower.
$1$. Walnut: Simple fruit (drupe).
$2$. Poppy: Simple fruit (capsule).
$3$. Fig: Composite fruit (syconus).
$4$. Radish: Simple fruit (siliqua).
$5$. Pineapple: Composite fruit (sorosis).
$6$. Apple: False fruit (pome).
$7$. Tomato: Simple fruit (berry).
$8$. Mulberry: Composite fruit (sorosis).
Therefore,the plants that produce composite fruits are Fig,Pineapple,and Mulberry.
The total count is $3$.

(B) An aggregate fruit is formed from a single flower that has a multicarpellary apocarpous (free carpels) gynoecium.
Each free carpel develops into a fruitlet,and these fruitlets together form an aggregate fruit.
Examples include strawberry,raspberry,and custard apple.
In contrast,simple fruits develop from a single ovary,and composite fruits develop from an entire inflorescence.

(C) In a tomato $(Solanum \text{ } lycopersicum)$, the fruit is a berry. The edible parts of the tomato fruit are the fleshy placenta and the pericarp (fruit wall).
Apple is a false fruit where the thalamus is edible.
Banana is a parthenocarpic berry where the mesocarp and endocarp are edible.
Potato is a stem tuber, not a fruit.

(C) geocarpic fruit is a fruit that develops underground.
In $Arachis hypogaea$ (groundnut),after fertilization,the flower stalk (gynophore) elongates and pushes the ovary into the soil.
The fruit then matures and develops underground.
Therefore,groundnut is known as a geocarpic fruit.

(D) An aggregate fruit is formed from a single flower that has a multicarpellary,apocarpous gynoecium.
In an apocarpous ovary,the carpels are free from each other.
Each individual carpel develops into a small fruitlet,and the entire collection of these fruitlets,which are attached to a common receptacle,is known as an aggregate fruit or $etaerio$.

(D) Dispersal is a universal biological need. For non-aquatic,terrestrial plants,the wind is an obvious supplier of energy for movement,and many plant adaptations exist that clearly take advantage of this fact. This type of seed dispersal is not efficient,but very effective. Appendages of some fruits and seeds act as parachutes; for example,seeds of cotton possess hair that help in the dispersal of these seeds by wind. Another well-known example is the dandelion.

(N/A) $\rightarrow$ The fruit is a mature or ripened ovary, developed after fertilisation. If a fruit is formed without fertilisation of the ovary, it is called a parthenocarpic fruit.
$\rightarrow$ Generally, the fruit consists of a wall or pericarp and seeds. The seed is enclosed by the pericarp in a fruit.
$\rightarrow$ The pericarp may be dry or fleshy. When the pericarp is thick and fleshy, it is differentiated into the outer epicarp, the middle mesocarp, and the inner endocarp.
$\rightarrow$ Drupe: In mango and coconut, the fruit is known as a drupe. They develop from monocarpellary superior ovaries and are one-seeded.
$\rightarrow$ In mango, the pericarp is well-differentiated into an outer thin epicarp, a middle fleshy edible mesocarp, and an inner stony hard endocarp.
$\rightarrow$ In coconut, which is also a drupe, the mesocarp is fibrous.

(N/A) Drupes are fruits that develop from monocarpellary superior ovaries and are one-seeded.
In these fruits, the pericarp is well-differentiated into three layers:
$1$. Epicarp: The thin, outermost skin.
$2$. Mesocarp: The middle, fleshy, or fibrous part.
$3$. Endocarp: The hard, stony, innermost layer that encloses the seed.
Examples: Mango $(Mangifera \, indica)$ and Coconut $(Cocos \, nucifera)$.
In mango, the epicarp is thin, the mesocarp is fleshy and edible, and the endocarp is stony hard.
In coconut, which is also a drupe, the mesocarp is fibrous.

(N/A) $(i)$ Placentation: The arrangement of ovules within the ovary is known as placentation.
$(ii)$ Fruit: $A$ mature or ripened ovary,developed after fertilization,is called a fruit.

(N/A) Mango and coconut are drupe fruits. They develop from monocarpellary,superior ovaries and are one-seeded.
In mango,the fruit is differentiated into an outer thin epicarp,a middle fleshy edible mesocarp,and an inner stony hard endocarp.
In coconut,the edible part is the endosperm.
The milk of tender coconut represents the free-nuclear liquid endosperm,which later becomes cellular as it deposits along the inner wall of the endocarp.

(N/A) maize grain is technically a fruit because it develops from a mature ovary.
In maize,the fruit wall (pericarp) is fused with the seed coat to form a single unit.
This specific type of dry,indehiscent fruit is known as a $Caryopsis$.
Since it contains both the seed and the fused fruit wall,it is botanically classified as a fruit rather than just a seed.

(N/A) drupe is a type of fleshy fruit in which the pericarp is differentiated into three distinct layers: the outer epicarp,the middle fleshy mesocarp,and the inner stony,woody endocarp. Examples include mango and coconut.

(A) The pericarp is the part of a fruit formed from the wall of the ripened ovary. Its primary function is to provide protection to the developing seeds inside the fruit from environmental stress,pathogens,and mechanical injury. It also plays a crucial role in the dispersal of seeds.

(C) Fruits are broadly classified into fleshy fruits and dry fruits based on the nature of the pericarp.
In fleshy fruits,the pericarp is thick,fleshy,and differentiated into epicarp,mesocarp,and endocarp (e.g.,mango,orange,guava).
In dry fruits,the pericarp is thin,dry,and not differentiated into distinct layers.
Groundnut (Arachis hypogaea) is a type of dry fruit (specifically a legume or pod) where the pericarp becomes dry and hard at maturity.
Therefore,groundnut is not a fleshy fruit.

(D) The correct matching is as follows:
$(a)$ Fleshy fruit: Orange $(3)$ - It has a succulent pericarp.
$(b)$ Dry fruit: Mustard $(1)$ - It has a dry, dehiscent pericarp.
$(c)$ False fruit: Strawberry $(2)$ - In this, the thalamus also contributes to fruit formation.
$(d)$ Parthenocarpic fruit: Banana $(4)$ - It develops without fertilization.
Therefore, the correct sequence is $a-3, b-1, c-2, d-4$.

(B) Both Mango and Coconut fruits are classified as drupes. They develop from a monocarpellary superior ovary.
$(i)$ Correct: Both are drupes.
$(ii)$ Incorrect: In Mango,the mesocarp is edible,while in Coconut,the endosperm is edible. The endocarp is hard and stony in both.
$(iii)$ Correct: In Coconut,the mesocarp is fibrous,whereas in Mango,it is fleshy and edible.
$(iv)$ Correct: Both develop from a monocarpellary ovary.
Therefore,statements $(i)$,$(iii)$,and $(iv)$ are correct.

(D) Drupe is a fleshy,single-seeded,indehiscent fruit where the seed is enclosed within a hard,stony endocarp. Examples include mango,coconut,peach,and plum.

(B) Pome is a fleshy,syncarpous fruit that develops from an inferior ovary and is surrounded by a fleshy thalamus.
Examples of Pome fruits include $Apple$ and $Pear$.
$Mango$ and $Peach$ are examples of $Drupe$ fruits,which are characterized by a succulent mesocarp and a stony endocarp.
$Litchi$ is a nut-like fruit where the edible,fleshy part is an outgrowth from the base of the seed known as an $Aril$.

(D) drupe is a fleshy fruit that develops from a monocarpellary or syncarpous ovary.
In these fruits,the pericarp is differentiated into three layers: the outer epicarp,the fleshy middle mesocarp,and the inner stony,hard endocarp.
Because the endocarp is extremely hard and protects the seed,these fruits are commonly referred to as stone fruits.
Examples include mango,peach,and coconut.

(A) fruit that is bicarpellary (composed of two carpels),syncarpous (carpels fused together),and contains a pseudoseptum (a false septum called a replum) is known as a siliqua.
This type of fruit is characteristic of the family Brassicaceae,for example,$Brassica$ (mustard).
