Xylem is a specialized tissue in vascular plants that is primarily responsible for the distribution of water and nutrients from roots to stems and leaves. The xylem also provides mechanical support and storage to the plant.

Phloem is a specialized tissue in vascular plants that is primarily responsible for the distribution of food nutrients such as glucose (sugar) and amino acids from the leaves to various parts of the plant
