Which among the following are absent in the collenchyma?

Options

A. Chloroplasts
B. Vacuoles
C. Intercellular spaces
D. Pectin deposition

Answer

**Step-by-Step Solution:**

1. **Understanding Collenchyma**: Collenchyma is a type of simple permanent tissue in plants that provides mechanical support. It consists of living cells that have irregularly thickened cell walls.

2. **Identifying Characteristics**: The cell walls of collenchyma are primarily composed of cellulose and pectin. These components contribute to the thickness of the walls, which is essential for providing structural support to the plant.

3. **Analyzing the Options**:
- **Chloroplast**: These are present in collenchyma cells, as they are living cells capable of photosynthesis.
- **Vacuoles**: Vacuoles are also present in collenchyma cells, as they are characteristic of living plant cells.
- **Intercellular Spaces**: Collenchyma lacks intercellular spaces because the thickened walls fill the gaps between cells, and they do not serve a function for gas exchange.
- **Pectin Deposition**: Pectin is a significant component of the cell walls in collenchyma, contributing to their thickness.

4. **Conclusion**: Among the options provided, intercellular spaces are absent in collenchyma. Therefore, the correct answer is that intercellular spaces are the feature that is absent in collenchyma.

**Final Answer**: Intercellular spaces are absent in collenchyma.
