Where are the spore-containing sori of a fern found?
Answers
Answer:
The spore containing sori of a fern are usually found on the underside of their leaves.
Plants reproduce in different ways. They may have seeds, which are produced by the flower, they may multiply in the ground due to rhizomes, or they may have spores. Ferns are one of the plants that use spores to reproduce.

Hii..
Mature plants produce spores on the underside of the leaves. When these germinate they grow into small heart-shaped plants known as prothalli. Male and female cells are produced on these plants and after fertilisation occurs the adult fern begins to develop.
ferns are most abundant in the tropics. Arctic and Antarctic regions possess few species. On the other hand, a small tropical country such as Costa Rica may have more than 900 species of ferns—about twice as many as are found in all of North America north of Mexico.
