Which of these cells in a plant is apt to be nonliving ?

Options

A. Epidermal
B. Sclerenchyma
C. Collenchyma
D. Parenchyma

Explanation

To determine which of the cells in a plant is apt to be non-living, we can analyze the options provided: epidermal cells, sclerenchyma cells, collenchyma cells, and parenchyma cells.

### Step-by-Step Solution:

1. **Identify the Cell Types**:
- **Epidermal Cells**: These cells form the outer layer of the plant and are involved in protection and gas exchange. They are living cells.
- **Sclerenchyma Cells**: These cells provide structural support to the plant. They are characterized by thick, lignified cell walls and are typically dead at maturity.
- **Collenchyma Cells**: These cells provide support while still allowing for growth. They are living cells and have unevenly thickened cell walls.
- **Parenchyma Cells**: These are the most common type of plant cells and are involved in storage, photosynthesis, and tissue repair. They are living cells.

2. **Analyze Each Option**:
- **Epidermal Cells**: Living cells (incorrect option).
- **Sclerenchyma Cells**: Non-living cells due to lignification (correct option).
- **Collenchyma Cells**: Living cells (incorrect option).
- **Parenchyma Cells**: Living cells (incorrect option).

3. **Conclusion**:
The only cell type among the options that is non-living is **sclerenchyma cells**.

### Final Answer:
The cell in a plant that is apt to be non-living is **sclerenchyma cells**.
