Find odd one w.r.t. simple tissue :

Options

A. Aerenchyma
B. Collenchyma
C. Sclereids
D. Phloem

Answer

To solve the question of finding the odd one out with respect to simple tissue, we will analyze each option provided:

### Step 1: Understand Simple Tissues
Simple tissues are composed of only one type of cell. They include:
- **Parenchyma**: Living cells that are involved in storage, photosynthesis, and tissue repair.
- **Collenchyma**: Living cells that provide support, especially in young stems and leaves.
- **Sclerenchyma**: Dead cells that provide structural support and strength.

### Step 2: Analyze Each Option
1. **Erenchyma**: This is a type of parenchyma that contains air spaces, allowing for gas exchange. It is a simple tissue.
2. **Collenchyma**: This is a type of simple tissue that provides flexible support to growing parts of the plant.
3. **Sclerenchyma**: This is also a simple tissue, consisting of thick-walled cells that provide rigidity and strength.
4. **Phloem**: This is a type of vascular tissue responsible for the transport of nutrients and sugars. It is made up of different types of cells (sieve elements, companion cells, etc.), making it a complex tissue.

### Step 3: Identify the Odd One Out
From the analysis:
- Erenchyma, collenchyma, and sclerenchyma are all types of simple tissues.
- Phloem is a complex tissue made up of multiple cell types.

### Conclusion
The odd one out with respect to simple tissue is **Phloem**.
