Question

Agar-agar is commercially obtained from

• A. green algae
• B. blue-green algae
• C. brown algae
• D. red algae

Answer 1

The correct option is D red algae

Agar is a jelly-like material which is derived from red algae. It is extracted from seaweed and processed into flakes, powders and sheets. It is commonly used in Asian cuisines and as a flavourless vegan substitute for gelatin. The jelly material in algae is due to the presence of unbranched polysaccharides obtained from the cell walls of the red algae.
