How are positive geotropism of root and negative geotropism of stem useful together for a plant?
Answer and explanation
Correct answer: Root gets water and minerals in soil and stem grows towards light
Positive geotropism means that roots grow in the direction of gravity, generally downward into the soil. This places them where they can anchor the plant and absorb water and mineral salts. Negative geotropism means that the stem grows away from gravity, generally upward, helping leaves reach light for photosynthesis. These complementary responses support nutrition and stability, so option A is correct.
