The size of mitochondria in plant cell is

Options

A. 3.0-4.0 `mum` long
B. 2-4 `mum` long
C. `1-4 mum` long
D. `1.0-1.0 mum`

Answer

To determine the size of mitochondria in plant cells, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Function of Mitochondria**: Mitochondria are known as the powerhouse of the cell. They are primarily responsible for cellular respiration and ATP synthesis.

2. **Identify the Structure of Mitochondria**: Mitochondria are double membranous organelles, meaning they have an inner and outer membrane. They are also considered semi-autonomous organelles because they can replicate independently of the cell cycle.

3. **Research the Size of Mitochondria**: The size of mitochondria can vary, but in plant cells, they typically range in size.

4. **Determine the Size Range**: Based on biological studies, the size of mitochondria in plant cells is generally reported to be between 1 to 4 micrometers.

5. **Select the Correct Option**: Given the options provided (three to four micrometers, two to four micrometers, one to four micrometers, or one to one micrometer), the correct answer is that the size of mitochondria in plant cells is **1 to 4 micrometers**.

### Final Answer:
The size of mitochondria in plant cells is **1 to 4 micrometers**.
