Why do moss plants produce very large number of male gametes ? Provide one reasons. What are these gametes called ?

Explanation

Mosses are bryophytes and they need water for fertilization . They lay their flagelated male gametes that swim across the water to reach female gamete. During this process many of the male gametes are destroyed,. thus, moss plants produce very large number of male gametes so that even of some of the gametes get destroyed, the remaining can fertilize the female gametes. Their male gametes are called antherozoids.
