Waste laden cells of oligochaetes and polychaetes are

Options

A. Thesocytes
B. Elecytes
C. Follicular cells
D. Yellow cells

Answer

**Step-by-Step Solution:**

1. **Understanding the Question**: The question asks about the waste-laden cells found in oligochaetes and polychaetes, which are classes of annelids.

2. **Defining Key Terms**: The term "laden" means carrying, so we are looking for cells that carry waste.

3. **Identifying the Classes**: Oligochaetes and polychaetes are both classes within the phylum Annelida. Oligochaetes include earthworms, while polychaetes include marine worms.

4. **Researching Waste-Carrying Cells**: In annelids, specifically in oligochaetes and polychaetes, the cells responsible for waste processing and storage are known as chloragogen cells.

5. **Alternative Names**: Chloragogen cells are also referred to as "yellow cells" due to their color. This is important as it connects to the options provided.

6. **Evaluating Options**: The options given are:
- Thesocytes
- Alicytes
- Follicular cells
- Yellow cells

Upon evaluation, chloragogen cells (or yellow cells) are the correct answer.

7. **Conclusion**: The waste-laden cells of oligochaetes and polychaetes are known as yellow cells or chloragogen cells.

**Final Answer**: Yellow cells (chloragogen cells).
