Vedclass · Answer

(N/A)  Pollen tube StyleIt is the structure formed when pollen lands on a suitable stigma. It grows out of the pollen grain and travels through the style to reach the ovary.It is the middle elongated part of the carpel which provides a path for the pollen tube to reach the ovary after pollination.$(b)$ Fission in Amoeba Fission in Plasmodium$(i)$ It shows binary fission.$(i)$ It shows multiple fission.$(ii)$ The parent cell divides into two small,nearly identical daughter cells.$(ii)$ The parent cell divides into several small,nearly equal-sized daughter individuals.$(c)$ Fragmentation RegenerationIt is a mode of asexual reproduction where the parent body splits into two or more fragments,and each fragment develops into an organism under favourable conditions,e.g.,$Spirogyra$.It is the ability to regrow lost body parts; it is used as a mode of reproduction in some organisms like $Hydra$ and $Planaria$.$(d)$ Bud of Hydra Bud of BryophyllumIt is an outgrowth formed on the body by regenerative cells. These buds develop into tiny individuals and detach from the parent body to become independent.In $Bryophyllum$,buds are produced in the notches along the leaf margin. These buds fall on the soil and develop into new plants.$(e)$ Vegetative propagation Spore formationIt is a mode of asexual reproduction in which parts like the root,stem,and leaves develop into new plants under appropriate conditions.It is a mode of asexual reproduction commonly seen in organisms like fungi. They reproduce through spores,which are minute,single-celled structures protected by thick walls until they find a moist surface to grow.

Differentiate between the following:
$(a)$ Pollen tube and Style
$(b)$ Fission in Amoeba and Plasmodium
$(c)$ Fragmentation and Regeneration
$(d)$ Bud of Hydra and bud of Bryophyllum
$(e)$ Vegetative propagation and Spore formation.
