OrganellesThink: How does each help the cell maintain

NucleusControls the cell functionsContains DNA

Cell MembraneControls what goes in to or out of the cell

RibosomesBuild proteins

MitochondriaRelease energy for the cell

Endoplasmic Reticulum (E.R.)Can be rough (has ribosomes) or smoothPathway for proteins to move through cell

GolgiPacks up proteins and sends them off.

Cell WallProtects the cell, structureNot in animals, only plants and bacteria

ChromosomesMade of DNAContain genetic information

ChloroplastPhotosynthesis takes place hereMakes food from solar energy

LysosomeWaste disposal

VacuoleStores water Larger in plants
