  • The economic product of Stevia is obtained from which part of the plant?

    Question: The economic product of Stevia is obtained from which part of the plant?

    Options:

    (a) Flower (1)
    (b) Fruit (2)
    (c) Seed (3)
    (d) Leaves (4)

    ✅Explanation:
    Stevia is a natural sweetener and sugar substitute derived from the leaves of the Stevia rebaudiana plant. The leaves contain sweet-tasting compounds called steviol glycosides, which are about 200-300 times sweeter than table sugar but have negligible calories. These glycosides are extracted and purified to create stevia sweeteners.

    • Why Leaves are the Economic Product:
    Steviol Glycosides: The leaves are the primary source of the sweet-tasting steviol glycosides, the main component of stevia sweeteners.
    Concentration: The highest concentration of steviol glycosides is found in the leaves, making them the most valuable part of the plant for commercial production.
    Harvesting: Leaves are relatively easy to harvest and process compared to other plant parts like flowers, fruits, or seeds.
