The hairs on the leaf of the water fern help to trap and absorb water, nutrients, and gases from the surrounding environment. They also provide buoyancy to help the fern float on the water's surface.
Yes, water moss ferns do have fine hairs on their fronds. These hairs help with water absorption and can also trap moisture in humid environments.
Because osmosis is related to the movement of water molecules.
The spore containing sori of a fern are usually found on the underside of their leaves. In water ferns the spores are produced inside the sporocarps. (Novanet/Gradpoint, On the underside of a fern frond.)
Yes, ferns, depending on the type can be compound, or doubly compound.
The epidermis of a root is typically thicker and lacks stomata, whereas the epidermis of a leaf is thinner and contains stomata for gas exchange. Additionally, root epidermis may have root hairs for absorption of water and minerals, while leaf epidermis may have trichomes for protection or water regulation.
