Q. Cell organelle covered by a single unit membrane is

Options

A. a) Sphaerosomes
B. b) Peroxisomes
C. c) Glyoxisomes
D. d) All the above

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks for a cell organelle that is covered by a single unit membrane. This means we are looking for organelles that have only one membrane surrounding them.

2. **Identifying the Options**: The options provided are:
- A) Spherosomes
- B) Peroxisomes
- C) Glyoxisomes
- D) All of the above

3. **Analyzing Each Option**:
- **Spherosomes**: These are small organelles involved in lipid storage and are indeed covered by a single membrane.
- **Peroxisomes**: These organelles contain enzymes for oxidative reactions and are also surrounded by a single membrane.
- **Glyoxisomes**: Similar to peroxisomes, glyoxisomes are involved in the conversion of fatty acids to carbohydrates and are also covered by a single membrane.

4. **Conclusion**: Since all three organelles (spherosomes, peroxisomes, and glyoxisomes) are covered by a single unit membrane, the correct answer is option D) All of the above.

5. **Final Answer**: The cell organelle covered by a single unit membrane is **option D) all of the above**.
