Parenchyma cells are concerned with

Options

A. Secretion
B. Support
C. Carry oxygen
D. Storage of surplus food

Answer

**Step-by-Step Solution:**

1. **Understanding Parenchyma Cells**:
- Parenchyma cells are a type of simple tissue found in plants. They are characterized by their thin cell walls and large vacuoles.

2. **Analyzing the Options**:
- The question asks what parenchyma cells are concerned with, and we have four options to evaluate.

3. **Option 1: Secretion**:
- This option states that parenchyma cells are involved in secretion. However, secretion is primarily the function of epithelial tissues, not parenchyma cells. Therefore, this option is incorrect.

4. **Option 2: Support**:
- The second option suggests that parenchyma cells provide support. While some plant cells do provide support, parenchyma cells are not primarily responsible for this function. Other cell types, such as collenchyma and sclerenchyma, are more specialized for support. Thus, this option is also incorrect.

5. **Option 3: Carry Oxygen**:
- The third option claims that parenchyma cells carry oxygen. This function is not performed by parenchyma cells; instead, red blood cells, which contain hemoglobin, are responsible for oxygen transport in animals. Hence, this option is incorrect.

6. **Option 4: Storage of Surplus Food**:
- The final option states that parenchyma cells are involved in the storage of surplus food. This is indeed one of the primary functions of parenchyma cells, as they store starch, oils, and water. Therefore, this option is correct.

7. **Conclusion**:
- Based on the analysis of all options, the correct answer is that parenchyma cells are concerned with the storage of surplus food.

**Final Answer**: Parenchyma cells are concerned with the storage of surplus food.
