In mosses gametes are produced by ____; in ferns gametes are produced by ____
Answer:
In mosses, gametes are produced by the gametophyte generation. Mosses have a life cycle that alternates between a gametophyte, which produces gametes (eggs and sperm), and a sporophyte, which produces spores. The gametophyte generation is the dominant phase in mosses.
On the other hand, in ferns, gametes are produced by the sporophyte generation. Ferns have a life cycle that includes two distinct stages: the sporophyte and the gametophyte. The fern plant we commonly see in nature is the sporophyte generation, which produces spores. These spores develop into a tiny, heart-shaped structure called a gametophyte, which produces gametes through mitosis. The fusion of gametes then results in a zygote, which develops into a new sporophyte plant. The sporophyte generation is the dominant phase in ferns.
