Xylem and phloem difference table class 10

Xylem is the complex, dead and permanent tissue responsible for carrying nutrients and water, whereas phloem is the soft and permanent tissue play its role in transporting the food and other organic material produced by the green parts especially leaves by the process of photosynthesis Xylem and phloem are two different kinds of vascular tissues that are involved mainly in the process of transportation. These tissues tend to form a vascular bundle and they work together in the form of a single unit. Xylem possesses a unidirectional movement, whereas, phloem possesses a bidirectional movement Difference between xylem and phloem is an important aspect of Biology. Furthermore, these two are types of vascular tissues that exist in plants and they transport the essential materials among the various parts of the plants. Moreover, xylem and phloem constitute vascular bundles when they are together This article provides further explanations on the differences between xylem and phloem brainly. Take the time also to read through their similarities and learn how to write the difference between xylem and phloem class 9. Comparison Table ( Xylem Vs Phloem) Basic Terms: Xylem Tissues

Xylem is present in the center of the vascular bundles, deep in the plant and made up of xylem vessels, fiber and tracheids whereas phloem is located on the outer side of the vascular bundles and made up of phloem fibers, sieve tubes, sieve cells, phloem parenchyma and companion cells. Xylem fibers are small whereas phloem fivers are large Xylem: Phloem: Composed of tracheids, vessels,xylem parenchyma & xylem fibers. Composed of seive tubes, companion cells,phloem parenchyma & phloem fibers: Tracheids, vessels & xylem fibers are dead cells whereas xylem parenchyma is living: Phloem fibers are dead whereas companion cells & phloem parenchyma are living

Transportation of materials in phloem. Xylem tissue helps in the transport of water and minerals. Phloem tissue helps in the transport of food. The transportation of water is from upwards roots to aerial parts of plants. Food is transported in both upward and downward directions. Transport in the xylem requires physical forces such as. Fig.Xylem and phloem Vessels, tracheids of the roots, stems and leaves are connected to form a continuous system in xylem cells to transport water to all the parts of the plants. Cells in the roots which are in contact with the soil take up ions which creates a difference of concentration between the roots and the soil and therefore water moves.
