Parenchyma containing chloroplasts is known as:

Options

A. prosenchyma
B. chlorenchyma
C. aerenchyma
D. collenchyma

Explanation

To answer the question "Parenchyma containing chloroplasts is known as:", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Parenchyma**: Parenchyma is a type of simple permanent tissue in plants. It consists of living cells that are generally thin-walled and isodiametric (equal in all dimensions).

2. **Identify Types of Parenchyma**: Parenchyma can be modified for various functions. The question specifically asks about parenchyma that contains chloroplasts.

3. **Chloroplasts and Photosynthesis**: Chloroplasts are organelles responsible for photosynthesis. Therefore, parenchyma containing chloroplasts is involved in the process of photosynthesis.

4. **Identify the Correct Term**: The specific type of parenchyma that contains chloroplasts is known as "chlorenchyma." This type of parenchyma is primarily found in the leaves and is crucial for photosynthesis.

5. **Eliminate Other Options**:
- **Prosenchyma**: This is a type of parenchyma that is elongated and provides strength, but it does not contain chloroplasts.
- **Arenchyma**: This type has large air spaces and is found in aquatic plants, aiding buoyancy, but it also does not contain chloroplasts.
- **Cholenchyma**: This type provides flexibility and support but is not a form of parenchyma that contains chloroplasts.

6. **Conclusion**: Based on the definitions and characteristics discussed, the correct answer to the question is **chlorenchyma**.

### Final Answer:
Parenchyma containing chloroplasts is known as **chlorenchyma**.
