Question

what is pollen -pistil interaction? how the plant get the ability to do this?

Answer 1

in plants pistil is responsible for attracting the pollen grain s because it releases some chemicals by which pollen grains attract towards it.

Answer 2

1. The pistil has the ability to recognize the right type of pollen to promote post- pollination events through the process of pollen-pistil interaction. Pollen−pistil interaction is a dynamic process involving pollen recognition, followed by promotion or inhibition of the pollen. This interaction is mediated by chemical components of the pollen and the pistil. If the pollen is of the wrong type, the pistil prevents pollen germination.

2. It is the natural process in plants for the selection of right type of pollen for sexual reproduction.
