Question

All the events from pollen deposition on stigma until pollen tube enters the ovule are collectively known as:

• A.
  Fertilisation
• B.
  Pollination
• C.
  Pollen–pistil interaction
• D.
  Triple fertilisation

Answer 1

The correct option is C

Pollen–pistil interaction
POLLEN PISTIL INTERACTION - All events from pollen deposition on the stigma until pollen tubes enter the ovule are together called as pollen pistil interaction.

Fertilisation is fusion of male and female gamete and pollination is transferring the pollen grains from anther to the stigma of a flower.
So, the correct answer is 'pollen-pistil interaction'.
