Step 6th Science Structure Function

Transcript of Cell Structure Function (1)

  • THE CELLScienceIndicator 1Boston International School

  • Objective: To recognize living things and their main features, to value the importance of our bodies.

    Learning objective: Identify the importance of the cell and the function of its parts.

    Biblical Principle:So God created man in his own image, in the image of God created he him; male and female created he them.

  • The Cell All 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.

  • Cell PartsOrganelles

  • Surrounding the Cell

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

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

  • Inside the Cell

  • Nucleus Directs cell activitiesSeparated from cytoplasm by nuclear membraneContains genetic material - DNA

  • 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

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

  • RibosomesEach cell contains thousandsMake proteinsFound on ribosomes & floating throughout 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 BodiesProcess proteins for secretion.

  • 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

  • VacuolesMembrane-bound sacs for storage, digestion, and waste removalContains water solutionHelp plants maintain shape.

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

  • TOPIC: TISSUES CELLTISSUE ORGAN SYSTEM

  • Cells, Tissues, Organs, and SystemsA cell is the smallest unit of living matter; the building blocks of living things.Tissues are groups of cells working together to perform a certain job.Organs are groups of tissues that perform a certain function.Organs working together to carry out a certain life function are an organ system.

  • workshopWRITE THE NUMBER OF EACH KIND OF CELL IN THE CIRCLE OF THE MATCHING FUNCTION.
