Do companion cells have nuclei?
for example phloem .... doesnt have a nucleus ... and it needs a nucleus to survive ... thats why they have a companion cell which have a nucleus for them ...if u try to separate the companion cell from the phloem the phloem will die after some time
What are the three cells that has no nucleus?
Prokaryotes,red blood cells of mammals,seive cells of phloem
WHAT ARE THE ADAPTATIONS OF THE PHLOEM?
Phloem cells do not have a nucleus, and they have very few vacuoles. They act much like a sieve.
What is the main difference between mature xylem cells and mature phloem cells?
The main difference between mature xylem and phloem cells lies in their functions and structural characteristics. Mature xylem cells are primarily responsible for transporting water and minerals from the roots to the rest of the plant, and they are typically dead at maturity, forming hollow tubes for efficient flow. In contrast, mature phloem cells transport organic nutrients, particularly sugars, throughout the plant, and they remain alive at maturity, featuring living cells like sieve tubes and companion cells that facilitate this process.
Does mature red blood cells have chromosomes?
No, mature red blood cells do not have a nucleus or any DNA, including chromosomes. They eject their nucleus as part of the maturation process to make more space for hemoglobin, the oxygen-carrying protein in red blood cells.

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 kinds of cells has no nucleus?
Prokaryotic cells have no nucleus. In the human body, mature erythrocytes (red blood cells) have no nucleus.
Does a nucleus lack mature red blood cells?
It is actually the other way around - mature red blood cells lack a nucleus.
Which of the plant cells have no nucleus?
Parenchyma, companion, sieve tube, & xylem cells have no nucleus. But, those are only the cells with out a nucleus that are fuctional.
Mature red blood cells?
erythrocytes
Is phloem dead or alive?
Phloem is a living tissue in plants, responsible for transporting nutrients, particularly sugars produced through photosynthesis, from leaves to other parts of the plant. The primary components of phloem, such as sieve elements and companion cells, are alive at maturity, allowing for the active transport of substances. However, the sieve tube elements lose their nucleus and most organelles as they mature, but they still function as living cells.
Does mature red blood cells have chromosomes?
No, mature red blood cells do not have a nucleus or any DNA, including chromosomes. They eject their nucleus as part of the maturation process to make more space for hemoglobin, the oxygen-carrying protein in red blood cells.
What mature cells have a nucleus?
All mature cells in the human body have a nucleus, except for red blood cells. This includes cells such as muscle cells, nerve cells, and skin cells. The nucleus contains genetic material (DNA) that controls the cell's functions and activities.
