Bryophytes resemble algae in the following aspects

A thallus like plant body, presence of roots and autotrophic nutrition
B thallus like plant body, lack of vascular tissues and autotrophic nutrition
C filamentous body, presence of vascular tissue and autotrophic nutrition
D differentiation of plant body into root, stem and leaves and autotrophic nutrition.

Verified Solution

Answer & Solution

Correct Answer

(B) thallus like plant body, lack of vascular tissues and autotrophic nutrition

Step-by-step Solution

Detailed explanation

(B) thallus like plant body, lack of vascular tissues and autotrophic nutrition
Bryophytes resemble algae in their thallus-like plant body, lack of vascular tissues, and autotrophic nutrition. Both groups have simple, non-differentiated structures and rely on photosynthesis for nutrition, but neither has the specialized vascular tissues, found in higher plants for transporting water and nutrients.

Apply the relevant identity from the chapter and substitute the values established in the previous step, keeping the original constraint in view.

Use the simplified expression to isolate the unknown, then plug the result back into the question setup to confirm the working is internally consistent.

Cross-check against a boundary or limiting case. Both the dimensional balance and the qualitative behaviour at the extreme should agree with the candidate answer.

Combine the steps above to identify the correct option. The remaining choices each fail at least one of the consistency, dimensional, or boundary checks.
