Question

Gas vacuoles are found in:
(A)
Chlorophyceae
(B) Phaeophyceae
(C)
Rhodophyceae
(D) Cyanophyceae​

Answer 1

Explanation:

ANSWER

Option A and C are correct as In Chlorophyceae, the stored food material is starch and the major pigments are chlorophyll a and b while, Floridian starch is the characteristic photosynthetic reserve substance of red algae, occurring abundantly in certain basin shaped grain cells. Most Rhodophyceae store starch outside the chloroplast, often as a cap over a bulging pyrenoid. The major carbohydrate storage product of red algae is a type of starch molecule (Floridian starch) that is more highly branched than amylopectin. Floridian starch is stored as grains outside the chloroplast. Thus, the correct answer is option C.
