how are xylem and phloem arranged in plant roots?
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 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.

Each teardrop-shaped vascular bundle consists of large xylem vessels toward the inside and smaller phloem cells toward the outside. Xylem cells, which transport water and nutrients from the roots to the rest of the plant, are dead at functional maturity.

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 cells make up vascular tissue, and phloem cells make up ground and dermal tissue.

Pressure from xylem water moves nutrients through the phloem. Why is it important that the xylem is adjacent to the phloem? ... This helps them survive in their arid surroundings because the high solute concentrations create relatively _____, which help reduce water loss.

Xylem tissue conducts water and mineral nutrients from the soil upward in plant roots and stems. It is composed of elongate cells with pointed ends called tracheids, and shorter, wider cells called vessel elements. The walls of these cells are heavily lignified, with openings in the walls called pits.

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.

In leaves, the vascular bundles are located among the spongy mesophyll. The xylem is oriented toward the adaxial surface of the leaf (usually the upper side), and phloem is oriented toward the abaxial surface of the leaf.

Xylem and phloem. ... One xylem and one phloem are known as a 'vascular bundle' and most plants have multiple vascular bundles running the length of their leaves, stems, and roots. Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds.

The phloem is the outer layer, and is sometimes referred to as the inner bark. It is a food conducting tissue. The xylem is located toward the inside of the cambium layer. The xylem is the vascular tissue through which most of the water and minerals of the tree are conducted.

The xylem and phloem are generally found together in vascular bundles and can lie in various positions relative to each other. A collateral arrangment has xylem and phloem next to each other with phloem to the outside and xylem to the inside.

The herbaceous stem is composed of vascular bundles (xylem and phloem) arranged in a circle around a central core of spongy tissue made up of parenchyma cells, called the pith. Surrounding the vascular bundles is a layer known as the cortex, which varies in thickness from species to species.

Xylem tissues are tubular-shaped structure, with the absence of cross walls. This tissue resembles the shape of a star. Phloem tissues are elongated, tubular-shaped structures that include thin sieve tubes with walls. Xylem occupies the centre of the vascular bundle.
988857
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.

Xylem. 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.
1017523
Yes, xylem bundles are also present in roots. in roots, xylem is exarch.

⭕️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.
