how are the xylem and phloem arranged in plant stems?
151518
- In the roots, xylem and phloem are in the centre to withstand stretching forces. - In the stems, they are arranged in bundles near the edge to resist compression and bending forces. - They are grouped together into veins and vascular bundles as they pass through leaves.

Xylem transports and stores water and water-soluble nutrients in vascular plants. Phloem is responsible for transporting sugars, proteins, and other organic molecules in plants.

Xylem consists mainly of dead cells phloem consists of living cells. Xylem conducts water and minerals whereas phloem conducts food materials. Xylem provides mechanical support whereas phloem can't provide mechanical support. Tyloses formation occur in xylem but not in phloem.

The xylem transports water and minerals from the roots up the plant stem and into the leaves. In a mature flowering plant or tree, most of the cells that make up the xylem are specialised cells called vessels.

They use two different systems - xylem moves water and mineral ions from the roots to the leaves - phloem moves food substances such as sucrose (sugar) and amino acids from leaves to the rest of the plant. This movement of food is called translocation .

Similarities between Xylem and Phloem Ø Both xylem and phloem are complex tissue composed of more than one type of cells. ... Ø Both contain parenchymatous cells. Ø Both contain fibres. Ø In primary vascular bundles both xylem and phloem are differentiated into proto- and meta- elements.

Which statement best describes the difference between xylem and phloem? Xylem transports water and nutrients in the plant, and phloem transports water and sugar.

Xylem tissue transports water and mineral ions, phloem tissue transports dissolved substances like sugars. Xylem and phloem are found throughout the plant (they transport materials to all parts). You just studied 7 terms!

Xylem parenchyma. The xylem is the vascular tissue responsible for the upward conduction of water and nutrients from the roots. The xylem tissue moves water and nutrients to various parts of the plant such as shoots and leaves. ... Parenchyma cells are the only living cells in the xylem.

Xylem and phloem in roots The xylem and phloem are grown within the central section of a root called a 'stele'. In eudicots, the xylem usually forms a cross of cells within the stele which runs the length of the root. Four independent phloem strands grow between each bar of the xylem cross.

What is the function of xylem and phloem? The woody tissue of a stem that carries water and dissolves minerals upward from the roots to the leaves. The vascular tissue in plants that transports food manufactured in the leaves to the rest of the plant.

Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap. The sap is a water-based solution, but rich in sugars made by photosynthesis.

Xylem and Phloem are two different types of vascular tissues which are mainly involved in the transportation process. These tissues form a vascular bundle, and these work together as a unit. The movement of xylem is unidirectional, while the movement of phloem is bidirectional.

Vascular tissue is made of two specialized conducting tissues: xylem and phloem. Xylem tissue transports water and nutrients from the roots to different parts of the plant, and also plays a role in structural support in the stem.

⭕️The main constituents of xylem are xylem tracheid, vessels and xylem parenchyma. ⭕️Here the main components are sieve tubes, companion cells and phloem parenchyma. ➖Xylem and Phloem consists of four different types of cells.
