(B) Chemically non-reactive
(C) Easily digested by animals
(D) Osmotically inactive
(E) Synthesised 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) and (D)

Explanation:

Carbohydrates are commonly found as starch in plant storage organs. It is chemically non-reactive and osmotically inactive polysaccharides of much greater molecules weight. Carbohydrates performs 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.
