class 12th CBSE Biology sample paper

Answer 1

All the events from pollen deposition on the stigma until pollen tubes enter the ovule are together referred to as pollen-pistil interaction.
This pollen-pistil interaction is a dynamic process involving pollen recognition followed by the promotion or inhibition of the pollen.
However, the knowledge gained in the area would help the plant breeder in manipulating pollen-pistil interaction even in incompatible pollination to get desired hybrid.

Answer 2

Pollen pistil interaction is one of the most essential and important life processes of the flower. The pollen-pistil interaction involves complex phenomenons like pollen adhesion, hydration and germination yet they are small things which can't be studied through our naked eye .This process is useful for survival of the species on the earth. It helps in reproduction .Without these process, The next generations may not be present
