The parenchymatous cells are

Options

A. Dead
B. Thick-walled
C. Thin-walled
D. Thick-walled and dead

Answer

**Step-by-Step Solution:**

1. **Understanding Parenchyma Cells**:
- Parenchyma cells are one of the three fundamental types of plant tissues. They are classified as simple permanent tissues.

2. **Characteristics of Parenchyma Cells**:
- These cells are primarily found in the soft parts of the plant, such as the cortex, pith, and medullary rays in stems and roots.
- Parenchyma cells are usually polyhedral (many-sided) in shape when closely packed, but can appear spherical when isolated.

3. **Living Status**:
- A key feature of parenchyma cells is that they are living cells. They remain capable of division (meristematic) even at maturity, which is a unique characteristic among plant cells.

4. **Cell Wall Structure**:
- Parenchyma cells have thin primary cell walls made up of cellulose and hemicellulose. This distinguishes them from other types of plant cells that may have thicker walls.

5. **Function**:
- The primary function of parenchyma cells is the storage of food, which can include starch, proteins, and fats.

6. **Evaluating the Options**:
- The options given are:
a) Dead
b) Thick-walled
c) Thin-walled
d) Thick-walled and dead
- Based on the characteristics discussed:
- Option (a) is incorrect because parenchyma cells are living.
- Option (b) is incorrect because they have thin walls, not thick.
- Option (c) is correct as parenchyma cells are indeed thin-walled.
- Option (d) is incorrect for the same reasons as (a) and (b).

7. **Conclusion**:
- The correct answer is option (c) Thin-walled.
