There are three criteria for something to be described as living/an organism: It must eat It must move of it's own accord It must be able to reproduce
Two things a cell must have are DNA and Ribosomes. Purposes DNA: Without DNA cells can't reproduce or the anythin really. Its like the brain of the cell , without it, you cant function properly. Ribosomes: They are a "must-have" organelle (the name for an organ in a cell) for protein production , the cell's food. Without the cell will "starve" and die.
Muscle cells,Skin cells, and white blood cells.
DNA replication must occur in the original cells before mitosis can take place. This ensures that each new cell receives a complete set of genetic information. During mitosis, the replicated DNA is separated and distributed to the new daughter cells.
Cells must be small in order to efficiently exchange nutrients and waste with their environment through their cell membrane. Smaller cells have a higher surface area-to-volume ratio, allowing for faster diffusion of materials. Additionally, smaller cells can efficiently and quickly transport molecules within the cell.
growth and division
There are many things that a cell must do in order to survive. Cells must for example absorb nutrients and take in water.
In multicellular organisms, cell division must be carefully regulated to ensure that growth of the organism is coordinated, replacement of dead cells takes place in an orderly fashion, and repair of injured cells is initiated when needed. Cell division must also be halted when growth and repair are completed. Cell division is controlled by a variety of factors. One of the most important controls is carried out by molecules called growth factors.

yes' because bacteria cells have a nucleus and all living things cells must have a nucleus

If it changed too fast then it would be difficult for the chromosomes to match up and offspring could not be produced. The quality must be maintained or proteins and other systems will not work correctly.
Cells must have two things: DNA and ribosomes. Without DNA, the cells cannot reproduce. Without ribosomes, proteins cannot be made or sent to other parts of the cell.
produce energy
No, it is not made of cells. All living things must be made of cells.

For things to be considered living they must meet some requirements. These are being able to grow, reproduce, adapt to their environment, and be composed of cells.
