The following type of tissue is usually absent in roots

Options

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

Answer

To determine which type of tissue is usually absent in roots from the given options, we will analyze each option step by step.

### Step-by-Step Solution:

1. **Understanding the Question**:
The question asks which type of tissue is usually absent in roots. We have four options:
- A) Parenchyma
- B) Meristem
- C) Collenchyma
- D) Sclerenchyma

2. **Analyzing Option A: Parenchyma**:
- Parenchyma is a type of tissue that consists of living cells and is involved in various functions such as storage, photosynthesis, and tissue repair.
- Parenchyma is indeed present in roots, where it plays a role in storage and other functions.
- **Conclusion**: Parenchyma is present in roots.

3. **Analyzing Option B: Meristem**:
- Meristematic tissue consists of undifferentiated cells that are capable of division and are responsible for the growth of the plant.
- The apical meristem is found at the tips of roots, contributing to root growth.
- **Conclusion**: Meristematic tissue is present in roots.

4. **Analyzing Option C: Collenchyma**:
- Collenchyma is a supportive tissue that provides flexibility and support to growing parts of the plant.
- It is primarily found in stems and leaves, particularly in areas that require support.
- **Conclusion**: Collenchyma is usually absent in roots.

5. **Analyzing Option D: Sclerenchyma**:
- Sclerenchyma is a type of supportive tissue that consists of thick-walled cells and provides rigidity and strength.
- This tissue can be found in various parts of the plant, including roots.
- **Conclusion**: Sclerenchyma is present in roots.

6. **Final Answer**:
- Based on the analysis, the type of tissue that is usually absent in roots is **C) Collenchyma**.
