Question

Bryophytes are not characterized by

• A. Alternation of generation
• B. Vascular tissues
• C. Presence of chlorophyll
• D. All of these

Answer 1

The correct option is B

Vascular tissues

The correct option is B.

Explanation for the correct option:

1. Organs such as leaves, and roots of vascular plants are defined by the arrangement of their vascular tissues.
2. Since bryophytes lack true vascular tissues, they also lack true leaves and roots.
3. However, many bryophytes have structures that are similar and functionally equivalent to leaves, so they are often referred to as such.

Explanation of incorrect option:

Option A:

1. Bryophytes have a heteromorphic alternation of generation, i.e. the sporophyte and gametophyte are distinctly different.
2. So, they are characterized by the alternation of generation.

Option C:

Like green algae, they produce chlorophylls a and b.

Final Answer: Bryophytes are not characterized by vascular tissues.
