Which of the following statement is correct?

Easy

A

Pollination gives the guarantee of the promotion of post-pollination events that lead to fertilisation
B

The events 'from pollen deposition on stigma until pollen tubes enter the ovule' are together referred to as Pollen-Pistil interaction
C

Pollen-pistil interaction is a dynamic process involving pollen rejection followed by only promotion (not rejection) of the pollen
D

Pistil has no ability to recognise the pollen, whether right or wrong type

Solution

Pollination does not give the guarantee of the promotion of post-pollination events that lead to fertilisation.
Pollen-pistil interaction is a dynamic process involving pollen recognition followed by promotion or inhibition of the pollen.
The pistil has the ability to recognise the pollen, whether it is of the right type (compatible) or of the wrong type (in compatible).
