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: -After traveling from the roots to stems through the xylem, water enters leaves via petiole (i.e., the leaf stalk) xylem that branches off from that in the stem.
Detailed explanation-3: -As water evaporates through the leaves, more water is pulled up through the roots of the plant. Nutrients and sugars from photosynthesis are dissolved in water and move from areas of high concentration, like the roots, to areas of lower concentration, such as the blooms, stem and leaves, for growth and reproduction.
