All cells stay alive due to the presence of nucleus. Once nucleus removed, the cell cannot sustain. It has been proved by an experiment on an amoeba cell. The nucleus is the main centre which controls all cell activities.
they must release chemical energy
The ribosomes take instructions from the RNA to make protiens.
the ribosomes help the cell stay healthy and alive
The three characteristics that show a cell is alive are the ability to reproduce, to grow and develop, and to respond to its environment. Cells must maintain these functions to stay alive and function properly.
No xylem die at maturity but phloem stays alive all the time the plant is alive.
It must obtain biological energy to stay alive.

No, they are not alive at all.

They might not have to eat all the time but I know that they must be constantly swimming in order to stay alive.
