Question

Reserve food material of algae is
A) Starch
B) Glycogen
C) Fat
D) Sugar

Answer 1

Most algae are photoautotrophic, because as their primary source of energy and biomass, they require only carbon dioxide and carbon dioxide.

Complete Answer:
For a wide and varied community of photosynthetic eukaryotic species, Algae is an informal name. It is a polyphyletic grouping, containing species from different different clades. Organisms range from single cell microalgae, like diatoms and chlorella, to multicellular forms, like the giant kelp, massive brown algae that can develop upto 50 m in length.

Now, let us find the solution from the options-
- In nature, algae may either be autotrophic or heterotrophic. Other external organic compounds, including energy sources and carbon, are needed for chemoheterotrophic algae. Starch, floridean starch, oils, laminarin, soluble carbohydrates, paramylon, and chrysolaminarin are the reserved food materials found in algae.
- Glycogen acts as one of two sources of energy stores, with short-term glycogen and the other type of long-term storage of triglycerides in adipose tissue. Thus, option B is not the correct option.
- Fats, along with proteins and carbohydrates, are among the three major macronutrient groups in the human diet. Thus, option C is not the correct option.
- The sort of real grass which stem is utilized is sugar cane, as it has a huge amount of sugar in it. Thus, option D is not the correct option.

Thus, the correct answer is option (A) Starch.

Note: As algae do not have a shared ancestor, algae form a polyphyletic group and while their plastids appear to get a single origin, they were obtained in various ways from Cyanobacteria.
