What are 4 functions cells must do to keep an organism alive?

Independent single-celled organisms must conduct all the basic processes of life: it must take in nutrients (energy capture), excrete wastes, detect and respond to its environment, move, breathe, grow, and reproduce. Even a one-celled organism must be organized to perform these essential processes.May 31, 2018

What are the 4 major functions that cells perform?
