Sate four different types of membranes on the basis of permeability

Explanation

To answer the question "State four different types of membranes on the basis of permeability," we can categorize membranes based on how they allow substances to pass through them. Here’s a step-by-step solution:

### Step 1: Define the Types of Membranes
1. **Impermeable Membrane**: This type of membrane does not allow any substances (neither solutes nor solvents) to pass through.
- **Example**: The cutinized cell wall, which is found in certain plant cells.

2. **Permeable Membrane**: This membrane allows both solutes and solvents to pass through freely.
- **Example**: Cellulosic membranes, which are found in plant cells and allow the movement of both types of molecules.
