Dominant phase of bryophytes bear

Options

A. Multicellular sex organs
B. Unicellular sex organs
C. Spore mother cells
D. Capsules

Answer

To solve the question regarding the dominant phase of bryophytes and what it bears, we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Dominant Phase of Bryophytes**:
- Bryophytes are non-vascular plants, and their life cycle consists of two main phases: the gametophyte and the sporophyte. The dominant phase in bryophytes is the gametophyte.

2. **Understand the Characteristics of the Gametophyte**:
- The gametophyte is the phase that is independent and photosynthetic. It is the green, leafy part of the bryophyte that we commonly recognize.

3. **Examine the Structure of the Gametophyte**:
- The gametophyte bears sex organs. In bryophytes, these sex organs are multicellular. The male gametophyte produces antheridia (male sex organs), and the female gametophyte produces archegonia (female sex organs).

4. **Differentiate Between Gametophyte and Sporophyte**:
- The sporophyte is dependent on the gametophyte and is generally smaller. It produces spores through meiosis, but it is not the dominant phase.

5. **Conclusion**:
- Since the question asks what the dominant phase of bryophytes bears, and we have established that the dominant phase is the gametophyte, which bears multicellular sex organs, the correct answer is that the dominant phase of bryophytes bears multicellular sex organs.

### Final Answer:
The dominant phase of bryophytes bears **multicellular sex organs**.
