Mature red blood cells (erythrocytes) are an example of cells that are dead when mature. They lose their nucleus and most organelles during the maturation process, which allows them to carry more oxygen but also means they cannot perform functions like protein synthesis or cell repair. Additionally, keratinocytes in the outermost layer of the skin become dead cells when they reach the surface, forming a protective barrier.

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.
Do xylem cells undergo cell division?
No, xylem cells are "dead" cells and therefore do not undergo cell division.
Does the spleen produce mature t-cells?
No, the spleen does not produce mature T-cells. T-cells mature in the thymus gland, not in the spleen. The spleen's main role is in filtering blood, storing red blood cells, and acting as a reservoir for immune cells.
The woody cells of a tree are formed from dead connective tissues true or false?
False. The woody cells of a tree are primarily formed from living cells called cambium that produce new layers of xylem and phloem, which then become part of the tree's structure as they mature and lignify. Wood cells themselves are actually dead at maturity and provide structural support to the tree.
What types of cells is DNA in?
Almost every cell (living or dead) contains DNA. There are a few very rare exceptions, including mature mammalian red blood cells (erythrocytes), which lose their contents to maximise oxygen carrying capacity. Young erythrocyte precursor cells, that will later become mature red blood cells, will contain DNA, as do red blood cells of other organisms (other than mammals).
What form chains with overlapping ends are dead when mature?
Water-conducting 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 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.

What are characteristics and uses of cork cells?
Cork is the outer protective tissue of older stems and roots. The mature cork cells become dead and filled with tannis, resins and air.
When was I'll Mature When I'm Dead created?
I'll Mature When I'm Dead was created in 2010.
Where are lymphocyte cells make?
They are made in the bone marrow, but B cells mature in the spleen and T cells mature in the thymus.
Do xylem cells undergo cell division?
No, xylem cells are "dead" cells and therefore do not undergo cell division.
Does the spleen produce mature t-cells?
No, the spleen does not produce mature T-cells. T-cells mature in the thymus gland, not in the spleen. The spleen's main role is in filtering blood, storing red blood cells, and acting as a reservoir for immune cells.
In which lymphoid organ do T cells mature?
T cells mature in the thymus, a lymphoid organ located in the chest.
What is the organ in which t cells mature?
T cells mature in the thymus The T-cells mature in both the thymus gland and the organs known as tonsils.
