The correct Answer is:
To determine what algae have in their cell walls, we can follow these steps: ### Step-by-Step Solution: 1. **Understand the Composition of Algal Cell Walls**: Algal cell walls are primarily composed of polysaccharides. The main components typically include cellulose, hemicellulose, and pectin. 2. **Evaluate the Options**: We have four options to consider: - Option 1: Cellulose, hemicellulose, and pectins - Option 2: Cellulose, galactans, and mannans - Option 3: Hemicellulose, pectins, and proteins - Option 4: Pectins, cellulose, and proteins 3. **Analyze Each Option**: - **Option 1**: Cellulose, hemicellulose, and pectins are all known components of algal cell walls. This option is likely correct. - **Option 2**: While cellulose is present, galactans and mannans are not typically found in algal cell walls. This option is incorrect. - **Option 3**: Hemicellulose and pectins are present, but proteins are not a major component of algal cell walls. This option is incorrect. - **Option 4**: Pectins and cellulose are present, but proteins are not a significant component in algal cell walls. This option is also incorrect. 4. **Conclusion**: Based on the analysis, the correct answer is **cellulose, hemicellulose, and pectins**. ### Final Answer: Algae have cell walls made up of **cellulose, hemicellulose, and pectins**. ---
