A meristem is the tissue in most plants containing undifferentiated cells (meristematic cells), found in zones of the plant where growth can take place. Meristematic cells give rise to various organs of the plant and keep the plant growing.
Meristematic tissue consists of actively dividing cells, and leads to increase in length and thickness of the plant. The primary growth of a plant occurs only in certain, specific regions, such as in the tips of stems or roots. It is in these regions that meristematic tissue is present.ylem is a chief, conducting tissue of vascular plants. It is responsible for conduction of water and mineral ions/salt. Xylem is a very important plant tissue as it is part of the 'plumbing system' of a plant. Think of bundles of pipes running along the main axis of stems and roots.
