What is the main role of pollen–pistil interaction?
Answer and explanation
Correct answer: To recognise compatible pollen and permit its germination
Pollen–pistil interaction enables the pistil to recognise compatible and incompatible pollen. Compatible pollen is accepted, germinates on the stigma, and forms a pollen tube that can grow toward the ovule. Incompatible pollen may be rejected through biochemical responses. The interaction is therefore related to pollen acceptance and fertilisation, not fruit colour, seed drying, or petal fall.
