Question

2) Leaflets of ferns Plants have brows
spots​

Answer 1

Explanation:

If you see small brown dots on the undersides of the leaves, they're probably sori, which are groups of sporangia that serve as spore cases. These spots may cover the entire underside of the leaf, but they aren't harmful to your plant. ... Once the female organs are fertilized by the male, small fern plants will grow.
