The document discusses the structure and function of cells. It defines cells as the basic unit of life and outlines cell theory. There are two main types of cells - prokaryotic and eukaryotic. A typical animal cell contains organelles such as a nucleus, cytoplasm, mitochondria and lysosomes, each with specific functions. A plant cell also contains chloroplasts for photosynthesis. The document provides details on the roles of various cell structures and organelles in supporting life processes.

2. Cell TheoryAll living things are made up of cells. Cells are the smallest working units of all living things. All cells come from preexisting cells through cell division.

5. Definition of CellA cell is the smallest unit of life that is capable of performing life’s functions of reproducing and getting food.

16. Inside the Cell

17. NucleusDirects cell activitiesSeparated from cytoplasm by nuclear membraneContains genetic material - DNA

18. Nuclear MembraneSurrounds nucleusMade of two layersOpenings allow material to enter and leave nucleus http://library.thinkquest.org/12413/structures.html

19. ChromosomesIn nucleusMade of DNAContain instructions for traits & characteristics http://library.thinkquest.org/12413/structures.html

20. NucleolusInside nucleusContains RNA to build proteins http://library.thinkquest.org/12413/structures.html

21. CytoplasmGel-like mixtureSurrounded by cell membraneContains hereditary material

22. Endoplasmic ReticulumMoves materials around in cellSmooth type: lacks ribosomesRough type (pictured): ribosomes embedded in surface http://library.thinkquest.org/12413/structures.html

23. RibosomesEach cell contains thousandsMake proteinsFound on ribosomes & floating throughout the cellhttp://library.thinkquest.org/12413/structures.html

24. MitochondriaProduces energy through chemical reactions – breaking down fats & carbohydratesControls level of water and other materials in cellRecycles and decomposes proteins, fats, and carbohydrateshttp://library.thinkquest.org/12413/structures.html

25. Golgi BodiesProtein 'packaging plant'Move materials within the cellMove materials out of the cellhttp://library.thinkquest.org/12413/structures.html

26. LysosomeDigestive 'plant' for proteins, fats, and carbohydratesTransports undigested material to cell membrane for removalCell breaks down if lysosome explodes http://library.thinkquest.org/12413/structures.html

27. VacuolesMembrane-bound sacs for storage, digestion, and waste removalContains water solutionHelp plants maintain shapehttp://library.thinkquest.org/12413/structures.html

28. ChloroplastUsually found in plant cellsContains green chlorophyllWhere photosynthesis takes placehttp://library.thinkquest.org/12413/structures.html
