Q17 / 465 · NTA Abhyas (NEET) 2020 · Chemistry · Biomolecules

Starch cannot be transported in plants because it is

  • A
    polymer of galactose.
  • Correct answer
    B
    present in the storage form.
  • C
    stachyose.
  • D
    polymer of sucrose.

Solution

Starch is the polymer of glucose and is a plant storage polysaccharide. It is mobilized into glucose. Sucrose is the form of sugar transported through phloem during translocation. Since it is soluble and less reactive it is an ideal form of sugar to transport.

Hence, the correct answer is option: 'B'.
