Cell wall materials found in Algal cell wall are

Options

A. Cellulose
B. Galactans
C. Mananns
D. All the above

Answer

To answer the question about the materials found in the algal cell wall, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Algal Cell Walls**: Algal cell walls are important structures that provide shape and protection to the cells. They are distinct from the cell walls of higher plants and fungi.

2. **Identifying Main Components**: The primary materials that make up the algal cell wall include:
- **Cellulose**: This is a polysaccharide that provides structural support and rigidity to the cell wall.
- **Galactans**: These are a type of polysaccharide that can also be found in the cell walls of algae, contributing to their structure.
- **Mannans**: Another type of polysaccharide that can be present in some algal species, adding to the complexity and functionality of the cell wall.

3. **Conclusion**: Therefore, the main materials found in the algal cell wall are cellulose, galactans, and mannans.

### Final Answer:
The cell wall materials found in algal cell walls are cellulose, galactans, and mannans.
