Practice questions testing deep understanding of osmosis, active transport, and root hair adaptations.
Q1. The concentration of mineral ions (like nitrates and potassium) inside a root hair cell is often 100 times higher than in the surrounding soil water. Despite this, the root continues to absorb these minerals from the soil. Explain the biological mechanism that allows this against the concentration gradient.
Q2. Assertion (A): Root hairs are exceptionally well-adapted for the absorption of water. Reason (R): They are covered with a thick, waterproof cuticle that prevents water from escaping back into the soil.
