The main structure for a living cell is the nucleai, and only because of it they can reproduce. The presence or not of nucleia (and specifically, nucleic acid) is what determine if an organism is alive or not.

everything inside a cell is used to help a cell live, grow and reproduce. What are you looking for specifically?

the cell membrane is a good place to start. the amoeba uses it to envelope their food and assimilate it into itself...also uses it to move around. the paramecium uses it's cillia (tiny hairs) on its membrane to sweep food into it's tiny lil' mouth. aww.... and the euglena...it um...well, i know it has a flagellum (tail that it uses to propel itself around). not too sure, but i think it has a mouth. its membrane doesn't do too much other than keep the insides...um..inside. euglenas are lame anyway. :D
