Question

Which of the following is a correct match of algal class with its characteristic reserve food?

• A. Chlorophyceae - Starch
• B. Phaeophyceae - Mannitol, laminarin
• C. Rhodophyceae - Floridean starch
• D. All of these

Answer 1

The correct option is D All of these

• Chlorophyceae have reserve food in the form of starch. Their cell wall is made up of cellulose.
• Phaeophyceae have reserve food in the form of laminarin and mannitol. The cell wall is composed of a mixture of polysaccharides like cellulose, pectose, and algin.
• Rhodophyceae have a cell wall composed of cellulose, pectin, and sulfated phycocolloids. They have reserved food as floridean starch.
• So, the correct answer is " All of these ".
