Q. New spherosomes develop from

Options

A. a) Old sphaerosomes
B. b) E.R.
C. c) Golgi apparatus
D. d) Prospherosomes

Answer

**Step-by-Step Solution:**

1. **Understanding Spherosomes**: Spherosomes, also known as oleosomes, are small organelles found in plant cells. They are involved in the storage and synthesis of lipids.

2. **Structure of Spherosomes**: These organelles are characterized by being enclosed by a single membrane, which is a phospholipid monolayer.

3. **Origin of Spherosomes**: The key aspect of the question is to identify where new spherosomes develop from. It is essential to know the origin of these organelles.

4. **Evaluating Options**:
- **Option A: Old spherosomes** - While spherosomes can be involved in lipid storage, they do not develop from old spherosomes.
- **Option B: Endoplasmic reticulum** - This is the correct answer. Spherosomes arise from the endoplasmic reticulum.
- **Option C: Golgi apparatus** - The Golgi apparatus is involved in processing and packaging proteins and lipids but does not directly give rise to spherosomes.
- **Option D: Prospherosomes** - This term is not commonly used in the context of spherosome development.

5. **Conclusion**: Based on the information, new spherosomes develop from the endoplasmic reticulum.

**Final Answer**: New spherosomes develop from the endoplasmic reticulum (Option B).
