Labeling Labels

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 protiens

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
