8. Chloroplast The green organelle that contains chlorophyll, where photosynthesis takes place http://virtualbiologytutor.co.uk/images/chloroplast1.gif http://imagecache.allposters.com/images/pic/JAG/03-PS05-8~Photosynthesis-Posters.jpg

9. Cytoplasm The jellylike substance that is between the cell membrane and the nucleus, carry out the transport of material http://daylilies.org/ahs_dictionary/cytoplasm.gif ?

10. Nucleus A large structure within a cell that controls the cell’s metabolism and stores genetic information (chromosomes and DNA) http://daylilies.org/ahs_dictionary/cytoplasm.gif ?

11. Ribosome Tiny structure in the cell that is the site of protein production http://publications.nigms.nih.gov/insidethecell/images/ch2_ribosome_ proteinbig.jpg

18. Centriole Cylindrical structure, located in the cytoplasm of the animal cell. Appears to function in cell division http://www.funhousefilms.com/centriol.jpg

19. Cell Wall Strong layer around the cell membrane primarily in plant and algae cells. Protects the cell http://terrebonneonline.com/bacteria2.jpg

20. Cell Respiration The process in which nutrients are broken apart, releasing the chemical energy stored in them http://www.phschool.com/science/biology_place/biocoach/images/cell resp/Overview.gif Chemical energy
