Labeling Organelles

Functions:
 1) Nucleolus : produces ribosomes, contains RNA.
 2) Nucleus : contains chromatin(DNA and protiens) and RNA, stores genetic information, controlls cell division, and directs functioning of the cell.
 3) Ribosomes :made of RNA and protien, site of protien synthesis, reads RNA code and translates into amino acid sequence.
 4) Vesicles : transport materials around or out of the cell, membrane bound sac, formed from pinching off of membrane of E.R.
 5) Rough E.R. : ribosomes on surface, network of tubules.
 6) Golgi Body : stacked flat sacs, accept vesicles on one side and produce them on the other side, storage and packing of molecules, modifys proteins.
 7) Cytoskeleton : protien filaments and tubules throughout cytoplasm, maintains cell shape, transport of vesicles and organelles.
 8) Smooth E.R. : lack ribosomes, network of tubules, packages protiens for transport, detoxifies liver cells, large surface area, sythesizes lipid triglyerides and steroids.
 9) Mitochondria : production of ATP (site of cellular respiration), powerhouse of the cell, double bound membrane.
10) Vacuole : membrane bound sac, larger than vesicles, storage.
11) Cytoplasm : gel substance within the cell membrane that holds together all the organelles.
12) Lysosome : contain digestive enzymes, garbage disposal, break down bacteria entering cell, intracellular digestion, manufactured by golgi body.
13) Centrioles : made of microtubules, help in cell division.
