Algae differ from Byroyphyta in possessing

Options

A. Chlorophyll a and b
B. Naked sex organs
C. Jacketed sex organs
D. Aerobic respiration.

Answer

To answer the question "Algae differ from Bryophyta in possessing," we need to analyze the options provided and understand the key differences between these two groups of organisms.

### Step-by-Step Solution:

1. **Understanding Algae and Bryophyta**:
- Algae are simple, photosynthetic organisms that can be unicellular or multicellular and do not have true roots, stems, or leaves.
- Bryophyta, commonly known as mosses, are more complex plants that have structures resembling roots, stems, and leaves but lack vascular tissue.

2. **Analyzing the Options**:
- **Option A: Chlorophyll A and B**:
- Both algae and bryophytes contain chlorophyll a and b, which are essential for photosynthesis. Therefore, this option is incorrect as it does not distinguish between the two.

- **Option B: Naked Sex Organs**:
- Algae possess naked sex organs, meaning their reproductive structures are not covered by protective layers. In contrast, bryophytes have jacketed sex organs, where the reproductive organs are surrounded by a sterile jacket. This is a significant difference between the two groups.

- **Option C: Jacketed Sex Organs**:
- This option describes a feature of bryophytes, not algae. Therefore, it is incorrect for the question asked.

- **Option D: Aerobic Respiration**:
- Both algae and bryophytes perform aerobic respiration, so this option does not differentiate between them and is also incorrect.

3. **Conclusion**:
- The correct answer is **Option B: Naked Sex Organs**, as this is a defining characteristic of algae that distinguishes them from bryophytes, which have jacketed sex organs.

### Final Answer:
Algae differ from Bryophyta in possessing **naked sex organs**.
