Asperm swims to and fertilizes an egg. The fertilized egg begins to grow, producing asporophyte plant, which grows attached to the gametophyte plants. Spores are produced bythe sporophyte plants in a capsule. When the spores ripen, they are shed. If they fall to asuitable place on moist ground, the spores begin to grow, producing the generation ofgametophyte plants.
