Question

Bryophytes resemble algae in the following aspects

• A. Filamentous body, presence of vascular tissues and autotrophic nutrition
• B. Differentiation of plant body into root, stem and leaves and autotrophic nutrition
• C. Thallus like plant body, presence of roots and autotrophic nutrition
• D. Thallus like plant body, lack of vascular tissues and autotrophic nutrition

Answer 1

Answer: (D)

Thallus like plant body, lack of vascular tissues and autotrophic nutrition

The similarities between bryophytes and algae are: The plants are usually thalloid in nature; the roots are absent and instead it is replaced by the root like unicellular or the multicellular structures called rhizoids; the cell walls are made up of cellulose; the reserve food materials are the starch; the mode of nutrition is autotrophic since it possesses chloroplast; vascular tissue like xylem and phloem are absent, which are the characteristics of higher plants; gametophytic phase is the dominant phase in the life cycle; formation of flagellate and motile sperms; usually whiplash flagella; water is needed for fertilization; the young gametophytic phases of most mosses are green and filamentous which resembles the thallus of green algae.

Hence the correct option is D.
