After a period of growth, the surface area to volume ratio is unsustainable. The cell would physically be unable to survive as a consequence (eg. it is unable to remove wastes or transport nutrients, etc.) so it divides to reach a more sustainable surface area to volume ratio.
This is beneficial for the organism because cells do die and need to be replaced.
Yes. But protein and water is more necessary.
Needed substances are carried to the body's cells by RBC's, or red blood cells. Red blood cells contain hemoglobin, a substance that allows proteins to bond to them. However WBC's(white blood cells) provide the body's cells with much needed protection.
The body uses the cell cycle for growth, development, tissue repair, and to replace old or damaged cells. It is essential for maintaining the normal functioning of the body and ensuring that new cells are produced when needed.
New cells are created by cell division.
Stem cells are needed because they become specialized cells within the body, helping organs regenerate and heal.

Nutrients are needed by body cells.
Nutrients are needed by body cells.
Yes. But protein and water is more necessary.
The replication of DNA forms new DNA which form new cells when put in the cells of new nucleus's. The body continuously needs to produce new cells through mitosis for growth and repair and therefore without DNA replication these new cells would not be able to be made, which are needed in the human body.
It is energy for our body's cells, that is broken down by the cells when energy is needed.
Protein helps to repair damaged cells and build new cells in place of the dead ones. Body builders use proteins to build up extra cells than actually needed.
