Cell Wall Supports and protects the cell and does not allow molecules in or out. (plant)
Chromosomes Proteins that contain DNA which has coded information for making molecules. (both)
RER - Rough Endoplasmic Reticulum produces and stores protein. (both)
SER - Smooth Endoplasmic Reticulum produces and stores fat. (both)
Golgi bodies Modifies and packages proteins from RER with enzymes. (both)
Ribosomes Helps the RER makes protein and is attached to the RER. (both)
Centrioles Helps with cell division and the spindle fibers come from here
Mitochondria Converts sugar into energy for the cell. (both)
Cytoplasm The fluid in the cell that allows organelles to move around. (both)

Lysosomes Breaks down food, invading bacteria and old/damaged cells. (animal)
Chloroplasts Uses sunlight to make its own food. (plant)
Diffusion movement of molecules from areas of high concentration to low concentration.
