Question

What is the definition of pollination?

Options

• Transfer of pollen grains from the stigma to the anther of a flower

• Movement of pollen grains within the flower's petals

• The fusion of pollen with the ovule to form seeds

• Transfer of pollen grains from the anther to the stigma of a flower

Answer 1

Pollination is specifically defined as the transfer of pollen grains from the anther (male part) to the stigma (female part) of a flower. This is a critical step that precedes fertilization. The pollen grains must reach the stigma for the process of fertilization to occur, as pollen grains themselves cannot move independently and require external agents for transport.
