What could happen to the reproductive process of mosses during a drought? The flagellated sperm would not be able to swim to the eggs for fertilization. The flagellated sperm and eggs would go dormant until water was available. Mitosis in the sporophyte would cease and the reproductive cycle would stop. Meiosis in the sporophyte would cease and the reproductive cycle would stop.

The answer is The flagellated sperm would not be able to swim to the eggs for fertilization.

Their life cycle of mosses has alternation of generation - a haploid gametophyte and a diploid sporophyte. Gametophyte produces haploid gametes which fuse to form a diploid zygote. The zygote grows into diploid sporophyte which produces haploid spores. The spores grow into gametophyte and the cycle begins again.

Mosses require water for reproduction. Before fertilization, the sperm swims to an egg through the water. Therefore, mosses require water for successful fertilization. In drought periods, without water, the sperm cell could not swim to the egg cell.
