BOTANY

Detailed explanation-1: -Wood is constituted by secondary xylem tissue, comprising parenchyma cells and conduits (vessels or tracheids).

Detailed explanation-2: -Xylem makes up the woody part of the tree that begins on the inside of the cambium. It extends through to the pith or the trunk center. Xylem is made up of living and non-living cells in roots, trunk, branches and foliage. It can be thought of as a pipeline from roots to leaves.

Detailed explanation-3: -Dead phloem tissue becomes the bark of a tree. The band of tissue just inside of the cambium is the xylem, which transports water from the roots to the crown. Dead xylem tissue forms the heartwood, or the wood we use for many different purposes.

Detailed explanation-4: -Wood is a structural tissue found in the stems and roots of trees and other woody plants. It is an organic material – a natural composite of cellulose fibers that are strong in tension and embedded in a matrix of lignin that resists compression.

Detailed explanation-5: -More technically, the cambium layer produces two different kinds of cells: xylem and phloem. Xylem is what eventually becomes wood; it grows inward from the cambium layer and acts as unidirectional vascular tissue, pulling water and other nutrients up from the roots to the top of the tree.
