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.

Why are cells from a blastula ideal to examine mitosis?
Unlike most cells in an adult body, an embryonic mass of cells is always dividing. Most cells in the adult body is quiscent and will not divide unless signals have been given to them to divide, and many cells such as muscle and nerve cells have even lost the ability to divide.
Why di cells need to divide?
cell division is how organisms grow.
What are three reasons why organisms need energy?
The cells of your body use energy in multiple ways. They use energy to maintain themselves and call reproduction called mitosis. In addition energy is used to carry out the cell's task such as carrying oxygen or attacking invading bacteria.
What can happen if your cells do not divide correctly?
I believe this kind of rapid growth is what characterizes tumor cells. Ideally, the body's immune system recognizes the rapidly growing cells and causes them to undergo protrammed cell death. However, if the cells have somehow developed a resistance to apoptosis, they'll just keep growing...
When does the cell need to copy the DNA-?
DNA ultimately controls all the cell's functions, so it is necessary to have it in all your cells. Every time your cells divide so that you can grow or repair your body, the DNA needs to duplicate so that it can be in each of your cells.
Why do the body cells and sex cells divide differently?
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.

Three reason your body need water?
to give you energy to keep your cells alive you could get dehydrates
What is the fastest human dividing cell?
The fastest dividing human cells are epithelial cells. These form the skin and line the cavities of the body. They need to divide quickly and replace themselves due to physical wearing away of the cells. Skin cells divide once every 20-30 minutes
What function does oxygen have in the body?
oxygen is solely used by mitochondria in cells for energy, that is the only reason we need oxygen.
Why do cell need to divide and produce new cells?
In order to replace the cells that are dieing
What cell divides infrequently?
Liver cells divide about once a year, and neurons (nerve cells) never divide once we are born (and when they are mature).
