__Nucleus:__
 * Contains and protects DNA
 * Passes DNA to daughter cells during cell division
 * Builds ribosomes
 * Copies DNA onto mRNA

__Rough Endoplasmic Reticulum:__
 * Makes more plasma membrane frome synthesized proteins and phospholipids
 * Folds proteins which are secreted by the cell or transported to other organelles
 * Transports proteins within the cell

__Smooth Endoplasmic Reticulum:__
 * Synthesis of lipids (fatty acids, phospholipids and sterioids)
 * Processes drugs and other harmful substances
 * Stores calcium ions for muscle contractions

__Ribosomes (free or attached):__
 * Site of protein synthesis
 * Translates mRNA into proteins

__Golgi Apparatus:__
 * Recieves and modifies proteins from the rough endoplasmic reticulum
 * Puts finished products into transport vesicles for extracellular transport

__Mitochondrion:__
 * Carries out cellular respiration by converting the chemical energy in foods to ATP (adenosine triphosphate)

__Centriole:__
 * Believed to play a role in the synthesis of spindle fibers during cell division

__Lyosome:__
 * Contains digestive enzymes
 * Breaks down food, bacteria, and damaged organelles

__Plasma membrane:__
 * Controls the passage of substances into and out of the cell.
