  • Cell Structure & Function

    http://koning.ecsu.ctstateu.edu/cell/cell.html

  • Cell Theory

    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.

  • Definition of Cell

    A 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 cell

  • Endoplasmic Reticulum

    Moves materials around in the cell

    transports of cellular materials

    packaging system

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

  • Cell Wall

    Most commonly found in plant cells & bacteria

    Supports & protects cells

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

  • Nucleus

    Directs cell activities

    Contains genetic material - DNA

  • Nucleolus

    Inside nucleus

    Contains RNA to build proteins

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

  • Chromosomes

    In nucleus

    Made of DNA

    Contain instructions for traits & characteristics

  • Cytoplasm

    Thick Gel-like mixture that protects the internal parts of the cell

  • Ribosome

    Each cell contains thousands of ribosome

    Make proteins and build structures

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

  • Mitochondria

    Produces energy (ATP) through chemical reactions breaking down fats & carbohydrates

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

  • Lysosomes

    Digestive 'plant' for proteins, fats, and carbohydrates

    Transports undigested material to cell membrane for removal

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

  • Vacuoles

    Membrane-bound sacs for storage, digestion, and waste removal

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

  • Chloroplast

    Usually found in plant cells

    Where photosynthesis takes place
