More mitochondria would be found in

Options

A. Meristematic cells
B. Epidermis
C. Companion cells
D. Xylem parenchyma

Answer

### Step-by-Step Solution:

1. **Understanding Mitochondria**: Mitochondria are known as the powerhouse of the cell, as they are responsible for producing energy in the form of ATP through cellular respiration.

2. **Identifying the Options**: The question provides several types of cells:
- Meristematic cells
- Epidermis cells
- Companion cells
- Xylem parenchyma cells

3. **Analyzing Meristematic Cells**:
- Meristematic cells are actively dividing cells found in plants.
- Since they undergo continuous cell division, they require a significant amount of energy, which means they need more mitochondria to meet their energy demands.

4. **Analyzing Epidermis Cells**:
- The epidermis is the outer layer of cells in plants and animals.
- These cells are not actively dividing and thus have fewer energy requirements compared to meristematic cells. Therefore, they contain fewer mitochondria.

5. **Analyzing Companion Cells**:
- Companion cells are associated with sieve tube elements in phloem and are involved in the transport of nutrients.
- They also have a relatively low energy requirement compared to meristematic cells, resulting in fewer mitochondria.

6. **Analyzing Xylem Parenchyma Cells**:
- Xylem parenchyma cells are involved in storage and transport of water and nutrients.
- Similar to the other cells mentioned, they do not require as much energy as meristematic cells, leading to a lower number of mitochondria.

7. **Conclusion**: Based on the analysis, the cell type with the highest number of mitochondria is the meristematic cells due to their continuous division and high energy requirements.

### Final Answer:
More mitochondria would be found in **meristematic cells**.
