Ferns often have small bumps called sori arranged in rows on their undersides. What are these structures?A) Spore capsules.
leva [86]

Answer:

A) Spore capsules

Explanation:

Ferns produce spore capsules contained in the sporangium (plural: sporangia), a structure localized on the undersides of the leaves. Moreover, the sporangia are borne in clusters known as sori (singular sorus). The spores are single reproductive cells that, when mature, are released from the sporangium to germinate on soil and produce new ferns. In a fern sporangium, the maximum number of spores is 64, although this number depends on the species.
