Explanation:
Detailed explanation-1: -How do plants take in nutrients and when do they need them? Once mineral nutrients are dissolved in soil water, they move into root cells by osmosis – the natural movement of water molecules from an area of high concentration to an area of low concentration.
Detailed explanation-2: -A long root enables the plant to reach deeper, more humid layers of soil, for example during drought. A shallower root with many root hairs is good for phosphate uptake, as phosphate is mostly found in the upper soil layers.
