Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds. Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems.

Webb2 sep. 2024 · Phloem are thinner tubes than xylem. They carry the glucose made in photosynthesis. They move the glucose from the leaves to wherever it is needed in the plant’s body. What does the xylem carry from plant to plant? A xylem cell will carry water using the elongated cells that it is made up of. WebbAnd thus, the water present in the xylem column transports up to the tip of the stem, leaves, etc. The direction for water and mineral in xylem is always unidirectional (up). Food and other organic substances (e.g., some plant hormones and even messenger RNAs) manufactured in the cells of the plant are transported in the phloem. WebbIt has been discovered that the angiosperm phloem can use the sieve tubes as a way to transport various forms of RNA to sink tissues which can help alter transcriptional activity. Sink tissues are tissues that are in the process of growth and need nutrients. shooglet
