Question

Give reasons why wind -pollinated flowers are small to produce pollen grains

Answer 1

Answer:

Why do pollen grains only produce tubes in flowers of their own species? ... If pollination is successful, a pollen grain germinates and a pollen tube grows down the style toward the ovary. The pollen tube goes through micropyle and discharges 2 sperm into the female gametophyte (embryo sac) within an ovule.
