In green algae outer and inner layer of cell wall is composed of (A) and (B) respectively

Options

A. (A) Cellulose (B) Hemi cellulose
B. (A) Cellulose (B) Pectin
C. (A) Pectose (B) Cellulose
D. (A) Lignin (B) Cellulose

Answer

To solve the question regarding the composition of the outer and inner layers of the cell wall in green algae, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of the Cell Wall**:
- The cell wall of green algae consists of two distinct layers: an outer layer and an inner layer.

2. **Identify the Outer Layer Composition**:
- The outer layer of the cell wall in green algae is primarily composed of **pectose**. Pectose is a polysaccharide that provides flexibility and is found in the outer cell wall.

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

4. **Summarize the Findings**:
- Therefore, for the question, the outer layer (A) is composed of **pectose** and the inner layer (B) is composed of **cellulose**.

5. **Select the Correct Option**:
- Based on the findings, the correct answer is:
- (A) Pectose
- (B) Cellulose

### Final Answer:
- (A) Pectose
- (B) Cellulose
