Carbohydrates are commonly found as starch in plant storage organs. Which of the following five properties of starch (a-e) make it useful as a storage material? (a) Easily translocated. (b) Chemically non-reactive. (c) Easily digested by animals. (d) Osmotically inactive. (e) Synthesized during photosynthesis. The useful properties are

Options

  1. A(B) and (C)
  2. B(B) and (D)
  3. C(A), (C) and (E)
  4. 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.
