The correct answer should be A. spores

Ferns don't have seeds and they reproduce using spores. Cones have seeds in them and seeds fall out. Pollen enters a flower and then the flower becomes a fruit. This is sexual reproduction of plants. Since ferns don't have this, they have to reproduce with spores.

What is an important quality of protocells?
Alecsey [184]
Protocells are self-organized, spherical collection of lipids. This is the proposed as the stepping stone to the origin life. One of the important qualities of protocells is its self-replicating, using the amphiphilic molecules. This requires repeatable set of chemical events.
