Cell Structure & Functionhttp://koning.ecsu.ctstateu.edu/cell/cell.htmlRed is your subject (left side)Navy Blue is your info (right side)Cell TheoryAll living things are made up of cellsCells 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 Cells

Amoeba ProteusPlant StemRed Blood Cell

Nerve Cell

BacteriaCell Partsaka OrganellesCell MembraneOuter membrane of cell that controls movement in and out of the cellDouble layer Nickname: Border PatrolAnalogy: Border

http://library.thinkquest.org/12413/structures.htmlNucleus Directs cell activitiesContains genetic material DNANickname: Control CenterAnalogy: City Hall

CytoplasmGel-like mixtureSurrounded by cell membraneNickname: JelloAnalogy: atmosphere (air)

RibosomesEach cell contains thousandsMake proteinsFound on Endoplasmic Reticulum & floating throughout the cellNickname: Ribs!!Analogy: Lumber Mill

http://library.thinkquest.org/12413/structures.htmlMitochondriaProduces energy through chemical reactions breaking down fats & carbohydratesNickname: PowerhouseAnalogy: Power Plant
