Cell Wall in algae is made up of

Options

A. Cellulose and hemicellulose with minerals like calcium carbonate
B. Cellulose, galactans, mannans and minerals like calcium carbonate
C. Cellulose, galactose, pectin and minerals like magnesium carbonate
D. Celluloser, galactose, mannans and chitin

Answer

To determine what the cell wall in algae is made up of, we can break down the components mentioned in the video transcript step by step.

### Step-by-Step Solution:

1. **Identify the Main Components**: The cell wall of algae is primarily composed of various polysaccharides. The transcript mentions several key components: cellulose, galactans, mannans, and calcium carbonate.

2. **Cellulose**: This is a common component found in the cell walls of many organisms, including plants and some algae. It provides structural support.

3. **Galactans**: These are a type of polysaccharide that can be found in the cell walls of certain algae. They contribute to the cell wall's structure and function.

4. **Mannans**: Similar to galactans, mannans are also polysaccharides that may be present in the cell walls of some algae.

5. **Calcium Carbonate**: This is another component that can be found in the cell walls of certain algae, particularly in those that form hard structures like coralline algae.

6. **Evaluate Options**: Based on the components identified, we can evaluate the provided options in the question to find the one that includes cellulose, galactans, mannans, and calcium carbonate.

7. **Select the Best Option**: After analyzing the options, the one that includes all these components is the best choice. According to the transcript, the most accurate option is option 2, which includes cellulose, galactans, mannans, and calcium carbonate.

### Final Answer:
The cell wall in algae is made up of cellulose, galactans, mannans, and calcium carbonate. The best option that includes all these components is **Option 2**.
