Question

Which of the following is/are aquatic and free floating fern?

• A. Azolla
• B. Salvinia
• C. Pteris
• D. Both A and B

Answer 1

The correct option is D Both A and B

Azolla and Salvinia are the two examples of the aquatic plants. These are the free floating ferns. The leaves are found floating on the level of the water surface and cover the complete surface of the water body. They are generally found in the still water bodies like lakes and ponds. They float by the mean of numerous, small, closely overlapping scale-like leaves with their roots hanging in the water.

Thus, the correct answer is option D.
