Question

Stored food of red algae is similar to:

• A. Chitin and mannitol
• B. Mannitol and glycogen
• C. Amylopectin and glycogen
• D. Glycogen and chitin

Answer 1

The correct option is C Amylopectin and glycogen

Stored food of red algae is similar in structure to amylopectin and glycogen. However, the degree of branching differs and is intermediary between the two.
In red algae, food is stored in the form of floridean starch. They are found in the cytoplasm outside the chloroplast of the cell, as small granules. They occur in the form of a cap over pyrenoid. Their structure is similar to that of amylopectin and glycogen.

Mannitol is stored food in brown algae.

Glycogen is the stored food in animals while starch is stored in plants.

Chitin is a structural amino polysaccharide mainly found in fungal cell wall and arthropod exoskeleton.
