Cell Membrane (gatekeeper) Semi-permeable Semi-permeable Controls what enters and leaves the cell Controls what enters and leaves the cell Gas exchange Gas exchange (similar function to lungs in your body) lungs in your body) 942/plcells/thinkquest/cellmembraen.j pg

Nucleus (Brain/Control Ctr.) Controls the activities of the cell Controls the activities of the cell Holds the genetic material (DNA) Holds the genetic material (DNA) Contains genes (made of DNA) on 46 chromosomes. Thousands of strands of DNA can fit onto one chromosome. These have all the instructions for your body. AnimalPhysiology/Anatomy/AnimalCellStructure/Nucleus/ cellnucleus.jpg
