A specialized parenchyma cell, located in the phloem of flowering plants and closely associated with the development and function of a sieve-tube element. Companion cells probably provide ATP, proteins, and other substances to the sieve-tube elements, whose cytoplasm lacks many structures necessary for cell maintenance.

What are Dead and live tissue of xylem and phloem?
in xylem all the cells R dead IN PHLOEM EXCEPT PHLOEM FIBRES ALL R LIVING CELLS
What are the constituents of phloem?
i) Sieve tubes (ii) Companion cells (iii) Phloem parenchyma (iv) Phloem fibres
How do pholem cells work?
A pholem is a tube that is made from living cells. Their function is to transport the glucose that is produced by photosysnthesis in the leaves to where it is needed. Pholem cells along with xylem cells produce vascular bundles.
What are the xylem and phloem are separated by?
A layer of cambium cells separates the xylem and phloem tubes.
What is the function of phloem cells in plants?
It trans locate food in plants mainly. Also transport some minerals,molecules ,hormones etc
Function of phloem parenchyma?
The parenchyma cells in between the sieve tubes of the phloem, and functions primarily for food storage.
What is the function of the cambium?
The cambium is the layer of actively dividing cells between the xylem and phloem tissues of plants. It is responsible for the secondary growth of plants.
Are phloem cells alive?
Yes, Phloem cells are alive.
what is the function of the bast of a tree?
It supports the conductive cells of the phloem and provides strength to the stem.
What are Phloem cells?
Phloem cells are living vascular cells that carries sugar and organic substances throughout a plant.
What is the difference between the cells that compose xylem and phloem tissue?
the cells of phloem are the only ones with cytoplasm
What are Dead and live tissue of xylem and phloem?
in xylem all the cells R dead IN PHLOEM EXCEPT PHLOEM FIBRES ALL R LIVING CELLS
Which structures make up phloem?
Phloem tissue consists of: conducting cells, generally called sieve elements; parenchyma cells, including both specialized companion cells or albuminous cells and unspecialized cells; and supportive cells, such as fibres and sclereids.(attribution: wikipedia, Phloem)
