The companion cell is responsible for all metabolic functions of the sieve tube member. The companion cell is essential for the survival of the sieve tube member. This will cause the member to cease phloem function and kill the plant.
WebPhloem cells. Phloem cells form tubes similar to xylem vessels, except the cells still retain some subcellular structures and are therefore living. Made of living cells (as opposed to … WebA substance called lignin strengthens the cell walls of xylem cells. Phloem cells. The phloem is specialised to transport food products to parts of the plant where they are needed. Phloem vessels are made up of columns of living cells. The end walls of phloem cells contain small holes to allow food products to move up and down the phloem vessels.
