phloem


Solution. Verified by Toppr. Phloem is a complex tissue it is made up of four types of elements: ∗ Sieve tube. ∗ Companion cells. ∗ Phloem fibers (bast fibers), and. ∗ Phloem parenchyma. Solve any question of Anatomy Of Flowering Plants with:-.



Together, xylem and phloem tissues form the vascular system of plants. Figure 25.4 B. 1: Xylem and phloem: Xylem and phloem tissue make up the transport cells of stems. The direction of water and sugar transportation through each tissue is shown by the arrows.



In (right) typical monocots, the phloem cells and the larger xylem cells form a characteristic ring around the central pith. The cross section of a dicot root has an X-shaped structure at its center. The X is made up of many xylem cells. Phloem cells fill the space between the X. A ring of cells called the pericycle surrounds the xylem and phloem.



At maturity, phloem is a living tissue but not with nucleus. Xylem cell comprises of xylem vessels, fiber and tracheids. Phloem comprises of phloem fibers, sieve tubes, sieve cells, parenchyma and companion cells. In xylem, the conducting cells or tracheary cells are dead with lignin thickening in the wall.
