Question

Statement-l: Cell wall of red algae contains cellulose, pectin and polysulphate ester
Statement-11 : Floridean starch is the reserve food in Rhodophyceae members
(A) Statement-l is correct but Statement II is wrong
(B) Statement-l is wrong but Statement II is correct
(C) Both statements are wrong
(D) Both statements are correct​

Answer 1

Answer:

(c) Both statements are wrong

Answer 2

The answer is Statement-l is correct but Statement II is wrong

• The cell wall of red algae (Rhodophyceae) is composed of cellulose, pectin and polysulphate esters.

• Some of the red algae have a cell wall that is made up of mannan fibrils or xylan fibrils. Now let us see about the blue algae, its cell wall is made up of peptidoglycan layer.

• Pectin and polysulphate esters are present in the cell wall of red algae.

• The red algae possess complex composite cell walls made of cellulose, xylan or mannan fibrils and extensive matrix polysaccharides including the economically important carrageenan and agar.

• Food is stored as floridean starch in Rhodophyceae. Mannitol is the reserve food material of which group of algae? Food is stored as floridean starch in Rhodophyceae

• Floridian starch is the characteristic photosynthetic reserve substance of red algae, occurring abundantly in certain basin-shaped grain cells.
