Gametophytes are haploid (containing one set of chromosomes) and are the dominant phase in their life cycle. They produce the gametes, which are the sex cells.
Here's a breakdown of the gametes produced:
* Male gametophytes produce sperm, which are small and flagellated, allowing them to swim through water to reach the egg.
* Female gametophytes produce eggs, which are larger and non-motile.
The fusion of sperm and egg results in the formation of a diploid zygote, which develops into the sporophyte.
