Spores are carried by the wind away from the sporophyte that produced them. If a spore lands in an environment that has enough water and the temperature is moderate, it germinates. The image shows two gametophytes. Note that these plants are green and photosynthetic. The plants are heart-shaped.
Several antheridia are visible.
Note that these are round structures. Each of these contains sperm cells. Each archegonium is flask shaped. Two archegonia are shown in the image. The archegonium on the left clearly shows the egg cell.
