Answer:
Yes, the ferns and the mosses might have close relation to water plants.
Explanation:
The adaptations of mosses and ferns show that they are primitive species which are imperfectly adapted to live in a terrestrial environment. For example, the mosses do not possess roots so that they can get water from the soil. Also, the mosses lack vascular tissues which allow transportation of water in a plant. Both, mosses and ferns, require for reproduction. These characteristics show that they once had ancestors that lived in the water. Hence, the mosses and ferns have close relation with water plants.
