Explain in detail the functioning of xylem and phloem.
Answers
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. What is commonly referred to as ‘sap’ is indeed the substances that are being transported around a plant by its xylem and phloem.
The separation between plants that have veins and plants that do not is one of the great divides within the plant kingdom. This separates plants into vascular and non-vascular plants. 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. Phloem is responsible for transporting food produced from photosynthesis from leaves to non-photosynthesizing parts of a plant such as roots and stems.
PHLOEM
The phloem carries important sugars, organic compounds, and minerals around a plant. Sap within the phloem simply travels by diffusion between cells and works its way from leaves down to the roots with help from gravity. The phloem is made from cells called ‘sieve-tube members’ and ‘companion cells’.
hope this will help you .
Xylem is the vascular tissue in the plants that carries water throughout the plant body. The xylem forms a continuous network of channels connecting roots to all the parts of the plants body.
Phloem is the vascular tissue in the plants that carries food throughout the plant body. The food prepared by the leaves of the plants is transported to all the parts of the plant through phloem tissue.
