Axial parenchyma cells are usually thinner-walled than the imperforate tracheary elements with which they are associated. In plants, parenchyma is one of three types of ground tissue.Ground tissue is anything that is not vascular tissue or part of the dermis of the plant.In contrast to collenchyma and sclerenchyma cells, parenchyma cells primarily consists of all of the simple, thin walled, undifferentiated cells which form a large majority of many plant tissues. At maturity, xylem is a dead tissue, with no cell content. Plant tissues can be categorised based on their structure and functions performed. The parenchyma is a collection of cells, which makes up the ‘filler’ of plant tissues. Plant tissues are classified into two types: Meristematic tissues: Xylem is composed of dead cells and only living parenchyma cells, whereas the phloem is composed of living cells and only dead fibers. In secondary xylem ray parenchyma cells originate from the ray initials of cambium. The other simple permanent tissues are: Xylem definition is - a complex tissue in the vascular system of higher plants that consists of vessels, tracheids, or both usually together with wood fibers and parenchyma cells, functions chiefly in conduction of water and dissolved minerals but also in support and food storage, and typically constitutes the woody element (as of a plant stem).
