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 isnât 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.
This finding can be used to show that back in time there was more water on Earth than today. Although water covers 70 percent of the Earth's surface, water is actually a rare substance that represents just 0.05 percent of the Earth's total mass. Water has nevertheless played a crucial role in the emergence of life on Earth. Without water, the Earth would in all likelihood be a dead planet. The amount of water on the planet has not always been the same, however. A research group at the Natural History Museum of Denmark has discovered this by measuring how hydrogen isotope ratios in the oceans have changed over time.
