-Found only in Eukaryotic Cells

-A differentiated structure within a cell that performs a specific function

-Can think of them as your organs in your body:
   kidneys filter blood and produce urine, stomach digests food, etc

Cell Structures in Terms of a City
Cell Structure      
City Structure         
Cell Function              
Nucleus Town hall
 Where DNA is held; responsible for providing instructions to the cell
Mitochondria Power Plant
 Where cellular respiration occurs
Golgi apparatus
 Post office
 Packages proteins to be delivered
Endoplasmic reticulum
 Roads/Highways Synthesized proteins and lipids travel down the endoplasmic reticulum
Ribosome Factory Where proteins are synthesized
Vesicles/Vacuoles Garbage dump/storage
 Sac-like materials responsible for getting rid of debris
Membranes/Cell wall
 City border
 Regulates what goes in and out of the cell
Cytoplasm The foundation
 Holds the organelles in place; gives the cell structure
Chloroplast Solar energy plant
 Where photosynthesis occurs
Cytoskeleton  Infrastructure  Also gives the cell structure

Organelles

-Nucleus
-Mitochondria
-Endoplasmic Reticulum (rough and smooth)
-Golgi Apparatus
-Vacuoles
-Vesicles
-Centrioles

Special Structures of Plant Cells

Cell wall: rigid layer that surrounds the plasma membrane of the plant cell – supports and protects the cell
Central Vacuole: large structure commonly found in mature plants – stores substances and help plant tissues maintain shape
Plastids: Organelles in plants with a variety of functions – for example:
   Chloroplasts: photosynthetic organelles
   Chromoplasts: make and store other pigments – ie the pigments seen in flower colors
