how is xylem and phloem different?
5742
Xylem and phloem facilitate the transportation of water, minerals and food throughout the plant. Xylem carries water and minerals from the roots to the leaves. Whereas, phloem carries the food prepared by the leaves to different parts of the plant.

Xylem and phloem are the two types of vascular tissues, present in plants and together constitute vascular bundles. Their function is to efficiently transport the materials which can be food, water, nutrients, organic materials, etc. between the stems, roots, and leaves of plants.

Xylem and phloem are the conducting elements of vascular plants. They function in the transport of water, nutrients, sugars, proteins and RNA throughout the plant. ... In an amphivasal arrangement, the phloem is surrounded by a ring of xylem. In an amphicribral arrangement, xylem is surrounded by a ring of phloem.

The main difference between vascular and nonvascular plants is that a vascular plant has vascular vessels to carry water and food to all the different parts of the plant. The phloem is the vessel that transports food and the xylem is the vessel that transports water.

Phloem cells conduct food from leaves to rest of the plant. They are alive at maturity and tend to stain green (with the stain fast green). Phloem cells are usually located outside the xylem. The two most common cells in the phloem are the companion cells and sieve cells.

Xylem is found in the center of the vascular bundle, deep in the plant and made up of xylem vessels, fiber, and tracheids, whereas phloem is found on the outer side of the vascular bundle and made up of phloem fibers, sieve tubes, sieve cells, phloem parenchyma and companion cells.

Xylem is dead at maturity, while phloem is living. All other answer choices are true. Xylem is also thicker and more rigid, which allows for greater pressure during water transport.

Xylem and Phloem are the components of the vascular tissue system in plants. In the young parts of the stem, the xylem and phloem are together organized as vascular bundles. Both xylem and phloem are complex tissues which composed of more than one types of cells.

Plants have two transport systems - xylem and phloem . Xylem transports water and minerals. Phloem transports sugars and amino acids dissolved in water.

Similarity: Both stems and roots contain vascular tissues (xylem and phloem), the circulatory system of the plant. Difference: In herbaceous stems, the vascular tissues are contained in bundles; these bundles sit relatively near the surface of the stem.

Water is transported upwards from roots to aerial parts of plants in xylem and food in phloem is transported in both upward and downward directions. Other than that, transport in xylem requires physical forces such as transpiration pull, however transport of food in phloem requires energy in the form of ATP.

Xylem sap contains water, inorganic ions and a few organic chemicals. Phloem sap contains water and sugars.

XYLEM : 1) This tissue contains xylem vessels, tracheids. ... 4) the cells of this tissue are dead and works on the principle transpiration. PHLOEM : 1)it contains phloem vessels and companion cells. 2) It transports food and water to all parts of the plant.

INTRODUCTION:Xylem and pholem together form the vascularbundles. ... 3)Xylem gives mechanical strength to the plant. 4)Conduction of water by xylem is unidirectional i.e., from roots to apical parts of the plant. PHLOEM:1)It transport food material from the leaves to growing parts of the plants.

Xylem and phloem are the conducting elements of vascular plants. They function in the transport of water, nutrients, sugars, proteins and RNA throughout the plant. The xylem and phloem are generally found together in vascular bundles and can lie in various positions relative to each other.

Terms in this set (20) What is the principal difference between mature xylem and mature phloem cells? Mature xylem cells have dies, leaving behind only their cell walls. Mature phloem cells contain living cells. What are the three main functions of leaves?

Xylem brings water up from the roots into the rest of the tree. Like phloem, primary xylem forms in primary growth, and secondary xylem forms in secondary growth. ... The secondary phloem is crushed and compacted, though nothing happens to the xylem except that it stops growing.
