1 Cellular Life Unicellular organism – single celled organism Multicellular organism – organism w/ many cells

2 Cell Theory 1. All living things are composed of one or more cells. 2. Cells are the smallest, basic unit of life. 3. New Cells come only from other living cells.

3 Types of Cells Prokaryotes – NO membrane bound organelles (like your organs each serve a particular function to help keep you alive) –Mainly lacking a nuclear membrane Some have ribosomes –unicellular Eukaryotes – have membrane-bound organelles. –Mostly multicellular, although some exceptions exist.

4 Plasma Membrane Phospholipid bilayer –Polar outsides Likes water (__________) –Nonpolar insides (fatty acids – like oil in vinegar) Hates water! (_________) Helps maintain equilibrium Numerous proteins throughout –Mainly for transport in and out of cell http://home.earthlink.net/~shalpine/anim/Life/memb.htm

5 Macromolecules More advanced tutorial on Macromolecules Carbohydrates http://www.wisc-online.com/objects/index_tj.asp?objid=AP13104http://www.wisc-online.com/objects/index_tj.asp?objid=AP13104 Lipids http://www.wisc-online.com/objects/index_tj.asp?objid=AP13204http://www.wisc-online.com/objects/index_tj.asp?objid=AP13204 Proteins http://www.wisc-online.com/objects/index_tj.asp?objid=AP13304http://www.wisc-online.com/objects/index_tj.asp?objid=AP13304

6 Lipids Fats! –Long Chains of _______ ________. –Many different types Most common = triglycerides Phospholipids – 1 fatty acid replaced with phosphate group

7 Proteins Chains of Amino Acids Provide structure for tissues and organs and help w/ metabolism Amino acids – connected with covalent bonds (called __________________) Enzymes – proteins found in living things that change the rate of a reaction!

8 Carbohydrates Composed of carbon, hydrogen and oxygen bonded covalently. Monosaccharide – single sugar (glucose or fructose) Disaccharide – 2 sugar molecules bonded –Ie. ________ (table sugar!) Polysaccharide – multiple _________ bonded together. –Ie. Starch, Glycogen, Cellulose (plant sugar!)
