why are xylem and phloem considered as complex tissue?
530448
Xylem and phloem are known as complex tissues as they are made up of more than one type of cells. These cells work in a coordinated manner, as a unit, to perform the various functions of the xylem and phloem. ... Sieve tube elements are tube-like elongated structures associated with companion cells.

Both systems are similar in that they are both made up of a vast array of tubes. Humans have arteries, capillaries, and veins to move materials through the system, and plants have xylem and phloem to do the same thing. Both systems are moving a combination of liquids and solids.

Most plants have xylem and phloem and are known as vascular plants but some more simple plants, such as mosses and algae, do not have xylem or phloem and are known as non-vascular plants. ... Xylem tissue is used mostly for transporting water from roots to stems and leaves but also transports other dissolved compounds.

Xylem tissue helps in the transport of water and minerals. Phloem tissue helps in the transport of food. ... Transport in xylem occurs with the help of simple physical forces such as transpiration pull. Transport of food in phloem requires energy in the form of ATP.

Similarities between Xylem and Phloem Ø Both xylem and phloem are complex tissue composed of more than one type of cells. Ø Both are the components of vascular tissue system of plants. Ø Both contain living and dead cells.

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.
217228
In each vascular bundle, the xylem and phloem are separated by a substance called vascular cambium.

Xylem and phloem. The xylem and the phloem make up the vascular tissue of a plant and transports water, sugars, and other important substances around a plant. ... 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.

Answer: Xylem and Phloem are called conductin tissues as they are involved in the conduction of water and the food. Xylem -conducts water absorbed by the roots to different parts of the plant. Phloem - conducts food prepared in the leaves to various parts of the plant.

Xylem tissues are the tubular-shaped structure, with the absence of cross walls. This tissue resembles the shape of a star. Phloem tissues are tubular-shaped, elongated, structures with the presence of walls with thin sieve tubes. It is located in the centre of the vascular bundle.

Xylem and phloem in stems In eudicots, vascular bundles are arranged in a ring within the stem. Each vascular bundle is orientated with the xylem on the interior and the phloem on the outside of the xylem.

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.

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.

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.
