Question

Which group of algae store polysaccharide laminarin in their cells?

• A. Green algae
• B. Blue green algae
• C. Red algae
• D. Brown algae

Answer 1

Answer: (D)

Brown algae

The major seaweeds of the world are the multicellular brown and red algae. The brown algae belong to the phylum Phaeophyta and inhabit rocky shores in cooler regions. They have cellulose in their cell wall. They store their food as a unique carbohydrate or as oil, rather than as starch which is found in most of the other algae. They store food as the compounds mannitol (alcohol) and laminarin (polysaccharide).

So, the correct answer is option D.
