Unlike xylem (which is composed primarily of dead cells), the phloem is composed of still-living cells that transport sap and forms part of the plants vascular system.
The sap is a water-based solution, but rich in sugars made by the photosynthetic areas (mainly in the leaves). These sugars are transported to non-photosynthetic parts of the plant, such as the roots, or into storage structures.
Transport in the phloem is generally in a downward direction within the plant. food transport

What is the function of phloem fibers?
Phloem fibers provide structural support to the phloem tissue, helping it maintain its integrity and function in transporting sugars, hormones, and other nutrients throughout the plant. They also aid in defense mechanisms against pathogens and mechanical stress.
Function of phloem parenchyma?
Phloem parenchyma cells provide structural support to the phloem tissue and help in the storage of starch, lipids, and proteins. They also facilitate the transport of organic compounds such as sugars and hormones within the plant.
What is the function of the cambium?
The cambium is a layer of cells in plants that is responsible for lateral growth, producing new xylem and phloem cells. It plays a key role in secondary growth, increasing the width of stems and roots.
Is mature phloem tissue dead upon maturity?
No, mature phloem tissue is not dead upon maturity. Phloem tissue remains alive and functional, aiding in the transport of sugars and other organic compounds throughout the plant. The cells in mature phloem tissue are specialized for this function and typically stay alive for an extended period.
What does a phloem plant look like?
Xylems and phloems look alike due to their specialized structure and function. Xylem in the vascular plants consists of similar tissues of trachieds, vessels and xylem parenchyma and perform the same function of transportation of water and minerals, hence it looks similar in all such plants. Likewise phloem consists of sieve tubes, companion cells and phloem parenchyma and perform the same function of conduction of food material to different plant parts.
Function of xylem and phloem?
the xylem transports water and the phloem transports organic substances.
What is the function of the phloem in a leaf?
Phloem provides a passage for the downward movement of the food manufactured in leaves to various parts of the plant.
What is the function of xylem and phloem in plants?

Why is the difference between xylem and phloem important in a plant?
There is structural difference between xylem and phloem. This is because their function is also different. Had there been no difference in structure, how these could have performed different function?
What is the function of the vascular cambian in the woody stems?
produces xylem and phloem
What is the vascular bundle of stems made up of?
They are made up of xylem and phloem. The xylem's primary function is to transport water, while the phloem transports nutrients.
What is the function of phloem fibers?
Phloem fibers provide structural support to the phloem tissue, helping it maintain its integrity and function in transporting sugars, hormones, and other nutrients throughout the plant. They also aid in defense mechanisms against pathogens and mechanical stress.
Function of phloem parenchyma?
Phloem parenchyma cells provide structural support to the phloem tissue and help in the storage of starch, lipids, and proteins. They also facilitate the transport of organic compounds such as sugars and hormones within the plant.
What are the constituents of phloem?
The phloem consists mainly of sieve tubes, companion cells, phloem fibers, and parenchyma cells. Sieve tubes are responsible for transporting sugars and other organic compounds, while companion cells support sieve tube function. Phloem fibers provide structural support, and parenchyma cells store nutrients.
How is the function of the xylem different from the function of the phloem?
Xylem's main function is to transport water and minerals from roots to other parts of the plant, while providing structural support. Phloem transports organic nutrients like sugars from photosynthesis to various parts of the plant for growth and energy storage.
How does the phloem and xylem tubes performs the same function as the human circulatory system?

what is the function of the bast of a tree?
It supports the conductive cells of the phloem and provides strength to the stem.
