One of the major aspects of life is self replication, or reproduction. If cells didn't divide, then populations of organisms would not form, and evolution would be impossible. The more proximate cause is that as cells grow and ingest food, there is a limit to how big they can become before the cell wall no longer supports the cytoplasm. At or before this point, the cell must divide or it will lyse (split open) and die.
Cells are the basic building block of life. If they could not reproduce (by division, for example), then we could not grow or reproduce. In fact, we would not even exist. According to other questions on WikiAnswers, our skin replaces itself every 35 days, and our skeleton replaces itself every 7 years. That means that in 35 days, you would have no skin, and in seven years, you would have no skeleton. So keep singing "I will divide!", little cells!
Cells divide when they have reached surface area to volume ratio which no longer support diffusion of material into the call.
for the growth and development of the body!
So that a body ,of an animal or plant, can grow.
so we can think breath and do all thoese other things that we do now
to make more cells to develop more
Stem cells are cells that are able to divide continuously without specializing. These kind of cells are undifferentiated biological cells.
Medical Science desperately Rushes In.
yes, cells grow to an enlarged size and divide into two small cells (which each enlarge and divide as well). but the larger cells get, the more difficult it is for them to function and operate, so they remain within certain size boundaries, getting large enough to divide and halving, large enough to divide and halving.
To break down sugar and produce useful energy, the cells need many things, but most importantly they need ENZYMES.
For coordination of It's activities.
Cells divide as the zygote becomes a fetus with growth and development into babies when born, cells also divide with growth after birth into adulthood and to replenish and renew damaged or lost cells.
In order to replace the cells that are dieing
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
cell division is how organisms grow.
cell division is how organisms grow
Cells divide.
Cells are in endocytosis when they are not dividing, this is just maintaing life and growth to divide again.
Because body cells need to make genetically identical daughter cells and sex cells need to make genetically unique cells with half the genetic material of the parent cell.

yes. all skin cells divide and divide and divide all over your body.
Yes, endothelial cells divide. It is important that these cells divide to replace old/dead cells and to create new blood vessels.
yes. all skin cells divide and divide and divide all over your body.
