Cell wall of green algae made up of :-

Options

A. Inner layer of cellulose and outer layer of pectose
B. Outer layer of cellulose and inner layer pectose
C. Outer layer of chitin and inner layer cellulose
D. Outer layer of cellulose and inner layer chitin

Answer

To determine the composition of the cell wall of green algae, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Cell Wall Composition**: The cell wall of green algae is primarily composed of two layers. It is essential to identify these layers to answer the question correctly.

2. **Identifying the Outer Layer**: The outer layer of the cell wall in green algae is made up of pectins. Pectins are polysaccharides that contribute to the structural integrity and flexibility of the cell wall.

3. **Identifying the Inner Layer**: The inner layer of the cell wall is made up of cellulose. Cellulose is a polysaccharide that provides strength and rigidity to the cell wall.

4. **Combining the Information**: From the information gathered, we can conclude that the cell wall of green algae consists of an outer layer of pectins and an inner layer of cellulose.

5. **Choosing the Correct Option**: Based on the composition identified, the correct answer to the question is that the cell wall of green algae is made up of an inner layer of cellulose and an outer layer of pectins.

### Final Answer:
The cell wall of green algae is made up of an inner layer of cellulose and an outer layer of pectins.
