Collenchyma is
(a) Living with no reserve food
(b) Living with protoplasm
(c) Dead and hollow
(d) Dead with reserve food

Options

A. Living with no reserve food
B. Living with protoplasm
C. Dead and hollow
D. Dead with reserve food

Answer

**Step-by-Step Solution:**

1. **Understanding Collenchyma**: Collenchyma is a type of simple permanent tissue found in plants. It is characterized by its composition of living cells that provide support to the plant.

2. **Characteristics of Collenchyma**:
- **Living Cells**: Collenchyma cells are living and contain protoplasm.
- **Cell Wall Composition**: The cell walls of collenchyma are thickened at the corners due to the deposition of cellulose and pectin, which gives them their supportive function.
- **Absence of Intercellular Spaces**: Collenchyma cells typically do not have intercellular spaces, which means the cells are closely packed together.

3. **Evaluating the Options**:
- **Option (a)**: "Living with no reserve food" - This is partially correct as collenchyma is living, but it does contain protoplasm, which can serve various functions, including storage.
- **Option (b)**: "Living with protoplasm" - This is correct as collenchyma cells are indeed living and contain protoplasm.
- **Option (c)**: "Dead and hollow" - This is incorrect as collenchyma cells are living.
- **Option (d)**: "Dead with reserve food" - This is also incorrect as collenchyma cells are living and not dead.

4. **Conclusion**: Based on the characteristics of collenchyma, the correct answer is **(b) Living with protoplasm**.
