Question

What is the importance of the Pollen Grains​

Answer 1

Answer:

The pollen grain is the male gametophyte which contains the male gametes. The pollen grain is spherical and measures about 25-50 micrometers. It is surrounded by two layers as exine which forms the outer layer and intine which forms the inner layer. The generative cell divides to form the two male gametes.

Pollen grains are exploited in basic research, because pollen is representing a generation and a haploid (gametophyte) plant can be made from single pollen. They are also used for commercial purposes as health food support as well as medicine. Pollen grains are also responsible to cause human allergy.
