Plasma Membrane (Cell membrane)
|
Controls movement of substances into and out of the cell
|
|
|
Microvilli
|
Folds of the plasma membrane that increase the surface area of the cell to increase absorption or secretion
|
|
|
Nucleus
|
Contains DNA molecules and nucleolus- control center of cell
|
|
|
Nucleolus
|
Assembly site for robosomes, where they are made: has RNA inside
|
