In the members of green alage the cell wall is double layred outer cell wall is made up of pectose while inner cell wall composed of :-

Options

A. Cutin
B. Pectose
C. Cellulose
D. Liginin

Answer

To answer the question regarding the composition of the inner cell wall in members of green algae, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding the Structure of Green Algae Cell Walls**:
- Green algae have a unique cell wall structure that consists of two layers: an outer layer and an inner layer.

2. **Identifying the Composition of the Outer Cell Wall**:
- The outer cell wall of green algae is composed of pectose, which is a polysaccharide that provides flexibility and structure.

3. **Determining the Composition of the Inner Cell Wall**:
- The inner cell wall, in contrast to the outer layer, is primarily made up of cellulose. Cellulose is a polysaccharide that provides rigidity and strength to the cell wall.

4. **Eliminating Incorrect Options**:
- The options given are cutane, pectose, cellulose, and lignin.
- Since we already established that the outer wall is made of pectose, it cannot be the answer for the inner wall.
- Cutane and lignin are components typically found in higher plants, not in green algae.
- This leaves cellulose as the only viable option.

5. **Conclusion**:
- Therefore, the correct answer is that the inner cell wall of green algae is composed of **cellulose**.

### Final Answer:
The inner cell wall of green algae is composed of **cellulose**.
