Roots have all the following functions except?

• A. Anchor the plant in the soil
• B. Furnish physical support for the stem
• C. Store food
• D. Release water through stomata

Answer: (D)

Roots mainly serve to anchor the plant in the soil, absorb water and minerals, and store food. Anchoring helps keep the plant upright and stable, especially in wind or on slopes, while absorption brings in the water and nutrients the shoots need. Some roots also store carbohydrates as a reserve. Stomata are tiny openings on above-ground organs like leaves and green stems that regulate gas exchange and water loss. Roots lack stomata, so they do not release water through stomata. Water moves from roots upward through the xylem to the aerial parts, but the loss of water via transpiration happens at the leaves, not at the roots. So, releasing water through stomata is not a function of roots.
