Answer 2

Pollen grains are microscopic structures that vary in size and shape. Some are tiny orbs, while others are egg-shaped. Although too small to see individually, they can be seen by the naked eye in large quantities. You have probably noticed a bright orange-yellow coating on your car during springtime that closely resembles cheese powder from the macaroni and cheese box.

Viewed through a microscope, a pollen grain hardly looks real. An extremely durable body, it has a tough outer coating. This hardy coat offers great protection from the harsh outdoor environment. This is important because inside this tough shell lie two cells: the tube cell, which will eventually become the pollen tube, and a generative cell, which contains the male sperm nuclei needed for fertilization.
