Algae have cells made up of

Options

A. cellulose, galactans and mannans
B. hemicellulose, pectins and proteins
C. pectins, cellulose and proteins
D. cellulose, hemicellulose and pectins

Answer

To answer the question "Algae have cells made up of what?", we can follow these steps:

### Step-by-Step Solution:

1. **Identify the Basic Components of Algal Cells**:
- Algae, like other living organisms, have cells that are composed of various organic compounds.

2. **Recognize the Role of Polysaccharides**:
- Algal cells require polysaccharides, which are complex carbohydrates.

3. **Determine the Specific Polysaccharides Present in Algae**:
- The primary polysaccharide found in the cell walls of algae is **cellulose**.
- In addition to cellulose, algae also contain **mannans**, which are important for the structural integrity of the cells, especially in marine algae.

4. **Identify Other Components**:
- Another important component is **galactans**, which form a protective layer around the cells of algae.

5. **Summarize the Components**:
- Therefore, the main components that make up the cells of algae are **cellulose, mannans, and galactans**.

6. **Choose the Correct Option**:
- Based on the components identified, the correct answer to the question is option 1: **cellulose, galactans, and mannans**.

### Final Answer:
Algae have cells made up of **cellulose, galactans, and mannans**.
