The phloem is mainly composed of living cells (fibers are the only dead cells in the phloem). The xylem contains xylem vessels, fibers and tracheids. Phloem contains phloem fibers, sieve tubes, sieve cells, phloem parenchyma and companion cells. Xylem is present in the center of vascular bundles deep in plants.

What is a level 8 organization?

Organization can be defined as a group of cells that are similar in shape and function called an organization. They form the cellular tissue level, which is intermediate between cells and organ systems. Organs are then created by the combination of tissue functional groups.
