Question

Which of the following plants has high water retention capacity and is used to provide moisture to plants?

• A. Sphagnum
• B. Botrychium
• C. Marsilea
• D. Marchantia

Answer 1

The correct option is A Sphagnum

Sphagnum differs from all other mosses in a number of important ways. Sphagnum moss leaves are only one cell thick. They are made up of large empty, dead hyaline cells (the water containers) and narrow, living green cells containing chloroplasts. Like the leaves, sphagnum moss stems have large, empty hyaline cells with numerous pores to allow water movement up the plant.

Hence the correct option is A.
