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. Examples of Cells Amoeba Proteus Plant Stem Bacteria

Red Blood Cell Nerve Cell Two Types of Cells Prokaryotic Eukaryotic

Prokaryotic Do not have structures surrounded by membranes Few internal structures One-celled

organisms, Bacteria http://library.thinkquest.org/C004535/prokaryotic_cells.html Eukaryotic Contain organelles surrounded by membranes Most living organisms Plant

Typical Plant Cell http://waynesword.palomar.edu/images/plant3.gif Cell Parts Organelles

Surrounding the Cell Cell Membrane Outer membrane of cell that controls movement in and out of the cell Double layer

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 Inside the Cell Nucleus Directs cell activities Separated from cytoplasm by nuclear

membrane Contains genetic material - DNA Nuclear Membrane Surrounds nucleus Made of two layers Openings allow material to enter and

leave nucleus http://library.thinkquest.org/12413/structures.html Chromosomes In nucleus Made of DNA Contain instructions

for traits & characteristics http://library.thinkquest.org/12413/structures.html Nucleolus Inside nucleus Contains RNA to build

proteins http://library.thinkquest.org/12413/structures.html Cytoplasm Gel-like mixture Surrounded by cell membrane Contains hereditary material

Endoplasmic Reticulum Moves materials around in cell Smooth type: lacks ribosomes Rough type (pictured): ribosomes embedded in

surface http://library.thinkquest.org/12413/structures.html Ribosomes Each cell contains thousands Make proteins

Found on ribosomes & floating throughout the cell http://library.thinkquest.org/12413/structures.html Mitochondria Produces energy through

chemical reactions breaking down fats & carbohydrates Controls level of water and other materials in cell Recycles and decomposes proteins, fats, and carbohydrates

http://library.thinkquest.org/12413/structures.html Golgi Bodies Protein 'packaging plant' Move materials within the cell Move materials out of

the cell http://library.thinkquest.org/12413/structures.html Lysosome Digestive 'plant' for proteins, fats, and carbohydrates

Transports undigested material to cell membrane for removal Cell breaks down if lysosome explodes http://library.thinkquest.org/12413/structures.html

Vacuoles Membrane-bound sacs for storage, digestion, and waste removal Contains water solution Help plants maintain

shape http://library.thinkquest.org/12413/structures.html Chloroplast Usually found in plant cells Contains green

chlorophyll Where photosynthesis takes place http://library.thinkquest.org/12413/structures.html
