* Cells are generally isodiametric
* Cells may be spherical, oval, rounded, polygonal or elongated inn shape.
* Their walls are thin and made up of cellulose.
* The cells may either be closely packed or have intercellular spaces.
Above characters of cells related to which type of simple permanent tissue?

Answer

To determine which type of simple permanent tissue corresponds to the given characteristics, we will analyze each characteristic step by step.

### Step 1: Identify the Characteristics
The question provides several characteristics of the cells:
1. Cells are generally isodiametric.
2. Cells may be spherical, oval, rounded, polygonal, or elongated in shape.
3. Their walls are thin and made up of cellulose.
4. The cells may either be closely packed or have intercellular spaces.

### Step 2: Analyze the Characteristics
- **Isodiametric Cells**: This means that the cells have similar diameters, indicating uniformity in size.
- **Variety of Shapes**: The cells can take on different shapes (spherical, oval, etc.), which suggests versatility in function.
- **Thin Cell Walls**: The fact that the cell walls are thin and made of cellulose is a key indicator of certain types of plant tissues.
- **Intercellular Spaces**: The presence of intercellular spaces or closely packed cells suggests a tissue that can accommodate various functions, such as storage or photosynthesis.

### Step 3: Compare with Types of Simple Permanent Tissues
1. **Parenchyma**:
- Typically has isodiametric cells.
- Cells can be of various shapes.
- Thin walls made of cellulose.
- Can be closely packed or have intercellular spaces.

2. **Collenchyma**:
- Has thick, irregular cell walls.
- Provides support, but does not match the thin wall characteristic.

3. **Sclerenchyma**:
- Has thick, lignified walls.
- Primarily provides structural support and does not match the thin wall characteristic.

### Step 4: Conclusion
Based on the analysis, the characteristics provided in the question align perfectly with **parenchyma tissue**. This type of tissue is known for its thin cellulose walls, isodiametric shape, and the ability to have various shapes and intercellular spaces.

### Final Answer
The type of simple permanent tissue related to the given characteristics is **parenchyma**.
