How is downward growth of root and upward growth of stem a survival strategy of a plant?
Answer and explanation
Correct answer: Root takes water and minerals and stem receives light
The governing concept is directional growth coordinated by plant hormones and environmental stimuli. Roots usually grow downward, helping them anchor the plant and absorb water and mineral ions from soil. Shoots generally grow upward toward light, allowing leaves to photosynthesise effectively. Together these responses support nutrition, stability, and survival, so option A is correct. The other choices assign impossible functions such as making light, eating soil, hearing, or blood circulation.
