Describe the parts of a typical flower.

(N/A) Parts of a flower in Angiosperms :
$\rightarrow$ $A$ flower is the reproductive unit in angiosperms,meant for sexual reproduction.
$\rightarrow$ It has a central axis and is attached to the plant by a stalk called the pedicel.
$\rightarrow$ The swollen end of the pedicel is called the thalamus (or receptacle). Four different kinds of whorls are arranged successively on it.
$\rightarrow$ These are calyx,corolla,androecium,and gynoecium.
$\rightarrow$ Calyx and corolla are accessory organs,while androecium and gynoecium are reproductive organs.
$(i)$ Calyx: The outermost whorl of the flower,made up of sepals. Sepals are typically green and leaf-like,protecting the flower in the bud stage. Calyx can be gamosepalous (sepals united) or polysepalous (sepals free).
$(ii)$ Corolla: Located inside the calyx,composed of petals. Petals are often brightly colored and attractive to insects for pollination. Corolla can be polypetalous (petals free) or gamopetalous (petals united).
$\rightarrow$ Corolla exhibits a variety of shapes and colors,such as tube-shaped,bell-shaped,funnel-shaped,or wheel-shaped.
$\rightarrow$ $A$ flower containing both androecium and gynoecium is called a bisexual flower.
$\rightarrow$ $A$ flower having either only stamens or only carpels is called a unisexual flower.
