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 answer the question regarding the number of chloroplasts in Chlamydomonas and in mesophyll cells, we can break it down into two parts:

### Step 1: Determine the number of chloroplasts in Chlamydomonas
Chlamydomonas is a unicellular green alga that is known to have a single chloroplast. This chloroplast is crucial for the process of photosynthesis, which allows the organism to convert light energy into chemical energy.

**Answer for Step 1:** The number of chloroplasts in Chlamydomonas is **1**.

### Step 2: Determine the range of chloroplasts in mesophyll cells
Mesophyll cells are specialized cells found in the leaves of plants. They are responsible for photosynthesis and typically contain multiple chloroplasts. The number of chloroplasts in mesophyll cells can vary, but it generally ranges from 20 to 40 chloroplasts per cell.

**Answer for Step 2:** In mesophyll cells, the number of chloroplasts 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**.
