nucleus control center of cell
cytoplasm mostly water; organelles are embedded in it
organelles little structures inside of cells
cell membrane found in all cells; SEMI-PERMEABLE because it lets SOME some things into the cell but not others; maintains homeostasis for the cell, made of organic compounds (proteins and lipids)
cell wall found in plants ONLY; prevents the cell from bursting
mitochondria where cell respiration occurs; called the powerhouse of the cell, where ATP is made
cellular respiration the process of food in the cell being turned into energy
