Cell Basic unit of life Organelle Parts of a cell ("organ" of the cell system) Nucleus a membrane-bound organelle that contains the cell's chromosomes. Pores in the nuclear membrane allow for the passage of molecules in and out of the nucleus. Mitochondria a double-membrane-bound organelle found in most eukaryotic organisms. Mitochondria generate most of the cell's supply of adenosine triphosphate, used as a source of chemical energy. Chloroplasts organelles that conduct photosyn...
