Answer:
Germination
Step-by-step explanation:
The sporophyte reproduces asexually through spore formation. The spores are formed in a capsule. Once the spores are mature the capsule breaks releasing them. The spores germinate to form a gametophyte. The gametophyte produces gametes that fertilize forming an embryo. The embryo develops into a sporophyte that remain attached to the gametophyte for nourishment.
