Cell wall Supports and protect the cell and does not allow molecules in or out
Chromosomes proteins that contains DNA which has coded information for making molecules
Rough E.R. produces and stores proteins
Smooth E.R. produces and stores fats and oil
Golgi bodies Modifies and packages proteins from rough E.R. with enzymes
Ribosomes Helps rough E.R. make proteins and is attached to rough E.R.
Centrioles Helps with cell division (mitosis) and sprinkle fibers come from there
