D) None of these
Show Answer
Answer:
Correct Answer: C
Solution:
Blue-green algae, also called cyanobacteria, any of a large, heterogeneous group of prokaryotic, principally photosynthetic organisms.
Cyanobacteria resemble the eukaryotic algae in many ways, including morphological characteristics and ecological niches, and were at one time treated as algae, hence the common name of blue-green algae.
The process of photosynthesis goes on in cyanobacteria in the same manner as in plants. The storage food products in cyanobacteria are somewhat different from those of green plants.
The storage product is usually a starch like substance similar to glycogen and is different from the starch produced in plants. This is known as Cyanophycean starch.
So, the correct answer is ‘Cyanophycean starch resembling glycogen’.
