(a) Easily translocated.
(b) Chemically non-reactive.
(c) Easily digested by animals.
(d) Osmotically inactive.
(e) Synthesized during photosynthesis.
The useful properties are
(a) Easily translocated.
(b) Chemically non-reactive.
(c) Easily digested by animals.
(d) Osmotically inactive.
(e) Synthesized during photosynthesis.
The useful properties are
Options
- A(B) and (C)
- B(B) and (D)
- C(A), (C) and (E)
- D(A) and (E)
Correct answer
B. (B) and (D)
Step-by-step solution
Starch is a plant storage polysaccharide. It is chemically non-reactive and osmotically inactive polysaccharides of much greater molecular weight. Carbohydrates perform a vital role in living organisms. Starch and other polysaccharides serve as energy storage in plants, particularly in seeds, tubers, etc. which provide a major energy source for animals, including humans.
