Which of the following features is unrelated to collenchyma in plants?

Options

A. Cell wall thickening - Cellulose, hemi-cellulose and pectin deposition
B. Intercellular space - Well-developed
C. Main function - Mechanical support to growing plant parts
D. Chloroplast - May or may not be present

Answer

To determine which feature is unrelated to collenchyma in plants, we can analyze the characteristics and functions of collenchyma tissue. Here’s a step-by-step breakdown:

### Step 1: Understand Collenchyma Tissue
- **Definition**: Collenchyma is a type of plant tissue that provides support, particularly in growing parts of the plant.
- **Characteristics**: It is a living tissue, often green in color, and is characterized by unevenly thickened cell walls.

### Step 2: Identify the Features
We need to evaluate the following features:
1. Cell wall thickening
2. Presence of intercellular spaces
3. Main function as mechanical support
4. Presence of chloroplasts

### Step 3: Analyze Each Feature
1. **Cell wall thickening**: This is a characteristic of collenchyma, as its cell walls are thickened to provide support.
2. **Presence of intercellular spaces**: Collenchyma typically does not have intercellular spaces. This feature is more associated with parenchyma tissue.
3. **Main function as mechanical support**: This is a primary function of collenchyma, as it provides structural support to growing plant parts.
4. **Presence of chloroplasts**: While collenchyma may contain chloroplasts (allowing for some photosynthesis), their presence is not guaranteed.

### Step 4: Determine the Unrelated Feature
From the analysis:
- The feature that is unrelated to collenchyma is the **presence of intercellular spaces**. This is because collenchyma does not typically have intercellular spaces, which distinguishes it from other types of plant tissues like parenchyma.

### Conclusion
The feature that is unrelated to collenchyma in plants is the **presence of intercellular spaces**.
