Question

Which of the following are stored in the form of starch which serves as an internal energy reserve to be used as and when required by the plant?

A.

sunlight

B.

oxygen

C.

water

D.

carbohydrates

Correct option is D

The Correct Answer is: (D) Carbohydrates.
Explanation:
Plants store carbohydrates in the form of starch, which serves as an internal energy reserve. Starch is a polysaccharide made up of glucose units, and
plants use it as a storage form of energy that can be broken down into simpler sugars (like glucose) when the plant needs energy, especially during periods of low sunlight or during growth.
Information Booster:
  • Starch Storage: Plants store excess glucose produced during photosynthesis in the form of starch, primarily in roots, tubers, seeds, and fruits.
  • Energy Reserve: When the plant requires energy for growth or reproduction and cannot produce enough sugars through photosynthesis, starch is broken down into glucose and used as fuel.
  • Carbohydrates: Carbohydrates include sugars, starch, and cellulose. Starch, specifically, is the form of carbohydrate stored for later use in plants.
Additional Information:
  1. Sunlight: Essential for photosynthesis and Vitamin D production.
  2. Oxygen: Vital for respiration and energy production in cells.
