Question

Compared to the gametophytes of bryophytes, the gametophytes of vascular plants tend to be

• A. Smaller and to have smaller sex organs
• B. Larger and to have larger sex organs
• C. Smaller but to have larger sex organs
• D. Larger but to have smaller sex organs

Answer 1

The correct option is A

Smaller and to have smaller sex organs

The correct option is A.

Explanation of the correct option:

1. Bryophytes are non-vascular plants that are devoid of roots and vascular tissues.
2. They have a dominant gametophyte stage and produce structures known as the antheridia and archegonia, male and female gametes respectively.
3. Vascular plants are plants that have a specialized conducting system consisting of the xylem and phloem vessels.
4. These plants are larger and more complex compared to bryophytes.
5. In their life cycle, the sporophyte phase is more prominent than the gametophyte phase.
6. Thus, the gametophytes of vascular plants are smaller and have smaller sex organs.
7. Examples of Bryophytes: Marchantia, Riccia, Pellia, Porella, Sphaerocarpos, Calobryum.

Final answer: Compared to the gametophytes of bryophytes, the gametophytes of vascular plants tend to be smaller and have smaller sex organs.
