WebbA tree is a tall plant with woody tissue. Trees gather light for photosynthesis through their leaves; this process creates “food” for the tree. Most of a tree trunk is dead tissue and serves only to support the weight of the tree crown. The outside layers of the tree trunk are the only living portion. The cambium produces new wood and new bark. 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.
