Transcript of Cell Structure & Function

  • Cell Structure & Functionhttp://koning.ecsu.ctstateu.edu/cell/cell.html

  • 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.

  • Definition of CellA cell is the smallest unit that is capable of performing life functions.

  • The Cell structures and functions

  • Cell Membrane

    Outer membrane of cell that controls movement in and out of the cellhttp://library.thinkquest.org/12413/structures.html

  • Endoplasmic ReticulumMoves materials around in the celltransports of cellular materialspackaging system

  • Cell WallMost commonly found in plant cells & bacteriaSupports & protects cells

  • Nucleus Directs cell activities Contains genetic material - DNA

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

  • ChromosomesIn nucleusMade of DNAContain instructions for traits & characteristics

  • CytoplasmThick Gel-like mixture that protects the internal parts of the cell

  • RibosomeEach cell contains thousands of ribosomeMake proteins and build structureshttp://library.thinkquest.org/12413/structures.html

  • MitochondriaProduces energy (ATP) through chemical reactions breaking down fats & carbohydrateshttp://library.thinkquest.org/12413/structures.html

  • LysosomesDigestive 'plant' for proteins, fats, and carbohydratesTransports undigested material to cell membrane for removalhttp://library.thinkquest.org/12413/structures.html

  • VacuolesMembrane-bound sacs for storage, digestion, and waste removalhttp://library.thinkquest.org/12413/structures.html

  • ChloroplastUsually found in plant cellsWhere photosynthesis takes placehttp://library.thinkquest.org/12413/structures.html
