Question

The sperm-containing pollen grains of seed plants are dispersed by wind or animals to fertilize egg cells. Why is this type of sperm dispersal advantageous over that observed in non vascular plants and seedless vascular plants?

Answer 1

Water is not required for the fertilization.

Step-by-step explanation:

The plants can reproduce by the means of asexual reproduction and sexual reproduction. The pollen grains and egg cell fertilize with each other in the sexual reproduction.

The seedless vascular plants and non vascular plants required the means of dispersal for their fertilization. Their egg cell fuses with the pollen grains that are dispersed by animals or wind. Water is not required for the fertilization of the vascular plants.
