what role does water play with for reproduction?
What really happens is that the sporophyte grows out of the top of the gametophyte, so it looks like a headdress of some kind. In this image of stagshorn moss, the green leafy part is the gametophyte and the tall spindle on top is the sporophyte. The first thing bryophytes need to reproduce is water. Since they usually live in places that are moist at least some of the time, this isnât really a problem for bryophytes. However, they still wait until a rainy period to reproduce, because they need water to carry sperm to the eggs. Bryophyte reproduction happens in two ways, like with other plants.
