Are stone cells in pears alive?
no. the grit is a stone cells. stone cells are schlerenchyma, and therefore are dead cells at maturity.
Which cell types remain in a non-dividing stage and do not complete the mitosis?
muscle cells and nerve cells. E.G. Nerve cells can never be created again after they die.
Does a skin cell have a diploid number of 46?
92. That zygote would never reach maturity. It would be aborted very early if it ever divided at all
Are there visible nuclei in the sclerenchyma tissue?
The nuclei is not visible in the sclerenchyma tissue at maturity because the cells are usually dead.
Which type of plant cells dies at maturity and has strong thick cell walls that remain and provides support for the plant?
sclerenchyma
Which of the following types of blood cells does not have a nucleus at maturity?
red blood cells

Do heart muscle cells continue to divide when they reach maturity?
No.
Could a cell live without a nucleolus?
A cell would die without its nucleus as it is its "brain" which controls the cell. Only human red blood cells have no nuclei after maturity.
Which cell types remain in a non-dividing stage and do not complete the mitosis?
muscle cells and nerve cells. E.G. Nerve cells can never be created again after they die.
Which cell types remain in a non dividing stage and do not complete the mitosis?
muscle cells and nerve cells. E.G. Nerve cells can never be created again after they die.
What are some examples cells divide rapidly some not at all after maturity?
because
What cells lack cytoplasm at maturity are tough and thick walled?
Many plant cells become dead.Sclerenchyma,collenchyma are some.
Which cell type remain in a non-dividing stage and do not complete the mitosis process?
muscle cells and nerve cells. E.G. Nerve cells can never be created again after they die.
Which plant cells function in providing support and are dead at maturity?
Sclerenchyma cell
Which cells stop dividing when they reach maturity?
Usually when they die. There is also cells called lysosomes that commit 'cell suicide'. An example of this is when a fetus in a womb has gills. When the fetus starts developing lungs, the cells in the gills commit 'suicide' since they are no longer needed.
How long do cells last?
They last your whole life (not true) red blood cells: die and are made evry 3 weeks white blood cell: you never get more than you have brain cells: you can get any more (if you inhale carbon dinoxid some of the brain cells die, so do do it!)
