Correct option is D
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
- 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.
- Sunlight: Essential for photosynthesis and Vitamin D production.
- Oxygen: Vital for respiration and energy production in cells.
