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.

Difference between primary and secondary phloem?
Primary phloem is formed during the primary growth of a plant and consists of sieve tubes, companion cells, parenchyma, and fibers. Secondary phloem is produced during secondary growth and consists of sieve tubes, companion cells, axial and ray parenchyma, and fibers. Secondary phloem is typically thicker and contributes to the increase in girth of the plant.
Example of phloem?
Phloem is a type of plant tissue responsible for transporting organic nutrients, mainly sugars, produced during photosynthesis, from the leaves to other parts of the plant, such as the roots and fruits. It consists of sieve tubes, companion cells, fibers, and parenchyma cells. One common example of phloem in plants is the phloem bundles found in vascular bundles within the stems of plants like trees.
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 two cell types make up xylem amd phloem?
Xylem is composed of tracheary elements (such as vessels and tracheids) and fibers. Phloem is composed of sieve tube elements and companion cells.
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.
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.
What fibers surround the xylem and phloem tissues?
The xylem and phloem tissues in plants are typically surrounded by a layer of sclerenchyma fibers known as the vascular bundle sheath. These fibers provide structural support and protection to the conducting tissues of the plant.
What fibers surrounds the xylem and phloem?
The xylem and the phloem tissues are found in plants. Bast fibers surround the xylem and the phloem tissues in plants.
Function of xylem and phloem?
the xylem transports water and the phloem transports organic substances.
Difference between primary and secondary phloem?
Primary phloem is formed during the primary growth of a plant and consists of sieve tubes, companion cells, parenchyma, and fibers. Secondary phloem is produced during secondary growth and consists of sieve tubes, companion cells, axial and ray parenchyma, and fibers. Secondary phloem is typically thicker and contributes to the increase in girth of the plant.
What is a transverse section xylem and phloem?
A transverse section of xylem is a view of the xylem tissue cut horizontally, showing the arrangement of xylem cells such as tracheids, vessel elements, and fibers. Similarly, a transverse section of phloem is a cross-sectional view of phloem tissue, displaying the arrangement of sieve tubes, companion cells, and phloem fibers. Both xylem and phloem are vascular tissues found in plants that transport water and nutrients.
What makes new xylem and phloem?
The new xylem is produced by the division and differentiation of cells in the vascular cambium layer, while new phloem is produced by the division and differentiation of cells in the vascular cambium or the procambium during secondary growth in plants. These cells differentiate into xylem vessels, fibers, and phloem sieve tubes, companion cells, and fibers respectively.
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?

Which grouping consists of connecting of connecting fibers that enable the cell to function as a unit?
Cytoskeleton consists of connecting fibers that enable the cell to function as a unit.
What is the function of the sharpey's fibers?
The function of the sharpey's fibers were specialized collagen fibers that help attach a tendon to a bone by deep penetration into bone at right angels.
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?
