General Studies (CPO) General Science

"The liverworts grow usually in moist, shady habitats such as banks of streams, marshy ground, damp soil, bark of trees and

deep in the woods. The plant body of a liverwort is thalloid, e.g., Marchantia. The thallus is dorsiventral and closely appressed to

the substrate. The leafy members have tiny leaf-like appendages in two rows on the stem-like structures.”

The above statement signifies which of the following Bryophyta?

SSC CPO 10th Nov 2022 Shift 1

Selaginella

Salvinia

Liverworts

Sphagnum

- The statement describes liverworts, focusing on their habitat and structure.

- Liverworts thrive in damp, shady environments like stream banks and forest floors.

- Their plant body, or thallus, is usually flat (thalloid) and lies close to the ground, as in Marchantia.

- Leafy liverworts have small leaf-like structures arranged in two rows.

Let's briefly discuss the options:

- Selaginella: Not a bryophyte; it's a lycophyte. Different structure and habitat.

- Salvinia: Aquatic fern, not a bryophyte. Not relevant here.

- Liverworts: Correct answer. Matches the description in the statement.

- Sphagnum: A type of moss, not liverworts. Known for its peat-forming ability.
