Companion cells have the structure of a 'normal' plant cell. Sieve tubes don't have nuclei, tonoplasts and ribosomes. Also there are no sieve plates in a companion cell, whereas there are in sieve tubes.

What is the specialized cell that helps control the movement of sugars through sieve tubes called?
This is the companion cell.
What is the conducting cell type in phloem?
The vast majority, 96-99 %, of the cells consist of bovina cellulose. Occasionally, particularly in southeast arabia, they may consist of silica as well. Sieve tubes, companion cell and phloem parenchyma.
Where is the sieve tube located?
Sieve tubes are located in the phloem tissue of vascular plants.
What is a sieve phloem?
The cells having sieve like perforations in their cell walls present in phloem are the sieve tubes of the phloem.
Function of phloem parenchyma?
The parenchyma cells in between the sieve tubes of the phloem, and functions primarily for food storage.
What is the shape of companion cells?
Irregular and sometimes spherical depending on their position between the sieve tubes.
What is the diffference between xylem and phloem?
Xylem contains Vessels, trachieds and xylem parenchyma Phloem consists of sieve tubes, companion cells and phloem parenchyma
What is the specialized cell that helps control the movement of sugars through sieve tubes called?
This is the companion cell.

How do water- conducting cells differ from cells that transport food?
Xylem (water-conducting cells) are dead (no cytoplasm), and form long tubes called vessels (no end walls) The walls are thickened with ligninPhloem (food transport cells) are living (have cytoplasm) There are two cell types - sieve tubes which conduct the food - they have end walls with perforations (sieve plates) and have no nucleus and companion cells - they don't conduct food but have a nucleus and they support the sieve tubes
Where is the sieve tube located?
Sieve tubes are located in the phloem tissue of vascular plants.
What are the two tubes in a plant stem?
The two main tubes in a plant stem are the xylem and phloem. The xylem transports water and minerals from the roots to the rest of the plant, while the phloem transports sugars produced during photosynthesis to various parts of the plant for energy.
What is a sieve phloem?
The cells having sieve like perforations in their cell walls present in phloem are the sieve tubes of the phloem.
Do plants have a tubes?
Yes angiospermic plants have sieve tubes in their conducting tissues.
Function of phloem parenchyma?
The parenchyma cells in between the sieve tubes of the phloem, and functions primarily for food storage.
