The number of chloroplast in chlamydomonas is _ _ _ _ _ _ and in a mesophyll cell, it ranges between _ _ _ _ _ _.

Options

A. 1, 2 - 4
B. 2, 20 - 40
C. 20 - 40, 1
D. 1, 20 - 40

Answer

To solve the question, we need to determine the number of chloroplasts in Chlamydomonas and the range of chloroplasts in mesophyll cells.

### Step-by-Step Solution:

1. **Identify the number of chloroplasts in Chlamydomonas**:
- Chlamydomonas is a unicellular green algae that typically contains **one prominent cup-shaped chloroplast** per cell.

2. **Determine the range of chloroplasts in mesophyll cells**:
- Mesophyll cells, which are found in the leaves of plants, usually contain a higher number of chloroplasts. The typical range for the number of chloroplasts in mesophyll cells is between **20 to 40**.

3. **Combine the findings**:
- Therefore, the number of chloroplasts in Chlamydomonas is **1**, and in mesophyll cells, it ranges between **20 to 40**.

### Final Answer:
- The number of chloroplasts in Chlamydomonas is **1** and in a mesophyll cell, it ranges between **20 to 40**.
