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.

  • Examples of CellsAmoeba ProteusPlant StemRed Blood CellNerve CellBacteria

  • Cells, Cells, Cells!Contain organelles surrounded by membranesMost living organisms

    PlantAnimalhttp://library.thinkquest.org/C004535/eukaryotic_cells.html

  • Typical Plant Cellhttp://waynesword.palomar.edu/images/plant3.gif

  • Typical Animal Cellhttp://web.jjay.cuny.edu/~acarpi/NSC/images/cell.gif

  • Cell PartsOrganelles

  • Surrounding the Cell

  • Cell MembraneOuter membrane of cell that controls movement in and out of the cellDouble layer Outer limits of the cityhttp://library.thinkquest.org/12413/structures.html

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

  • Inside the Cell

  • Nucleus Directs cell activitiesContains genetic material DNALike the city hall or master computer of the cell

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

  • ChromosomesIn nucleusMade of DNAContain instructions for traits & characteristics

    http://library.thinkquest.org/12413/structures.html

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

  • CytoplasmGel-like mixtureSurrounded by cell membraneContains hereditary material Its the jello in fruit gelatin

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

  • Endoplasmic ReticulumMoves materials around in cellSmooth type: lacks ribosomesRough type (pictured): ribosomes embedded in surfaceThe highway of the cellhttp://library.thinkquest.org/12413/structures.html

  • 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

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

  • LysosomeDigestive 'plant' for proteins, fats, and carbohydratesTransports undigested material to cell membrane for removalThe trash compactor of the cell http://library.thinkquest.org/12413/structures.html
