2. Cell Theory 1.All living organisms are made of cells 2.Cells are the basic unit of life 3.All cells come from preexisting cells

4. Prokaryotic V Eukaryotic

5. Prokaryotes V Eukaryotes

6. Pro v Euk

7. Prokaryotic Eukaryotic No true nucleus No membrane bound organelles Bacteria, archaea True Nucleus Membrane-bound organelles Plants, animals, algae, yeast Both Have: 1.Ribosomes 2.DNA/RNA Because both have to make proteins! Recall: monomer of proteins

8. Plant VS Animal Cells

10. Plants ONLY have: Cell wall Large central vacuole Plastids (chloroplasts) http://www.diffen.com/difference/Animal_Cell_vs_Pla nt_Cell http://www.diffen.com/difference/Animal_Cell_vs_Pla nt_Cell *Plants typically don’t have centrioles, because plant cells are more rigid (discuss later in cellular division)

11. Quiz- write out true or false. CORRECT THE FALSE STATEMENTS by rewriting the statement correctly. 1.Prokaryotic cells have no DNA. 2.Eukaryotic cells include plants, animals, and bacteria. 3.The plasma membrane allows substances to go into and out of the cell with little regulation. 4.“All living things have 3 or more cells” is part of the cell theory. 5.Schwann studied plant cells. 6.Plant cells have a small vacuole and a cell wall. 7.Proteins are made in the mitochondria. 8.Only eukaryotic cells have ribosomes.

12. Plasma Membrane Internal Metabolism VS External Environment

13. Plasma Membrane

16. Plasma Membrane Details

18. P.M.

20. Phospholipid Phosphate + glycerol + fatty acid tail

21. Phospholipid

22. Fatty Acid Long chain of Hydrogen and Carbon with Carboxyl group at the end

23. Fatty Acid rxns: Recall Condensation: releases an H 2 O; building a polymer http://www.biotopics.co.uk/as/lipidcondensatio n.html Hydrolysis: requires H 2 O; breaking down a polymer http://www.biotopics.co.uk/as/lipidhydrolysis.ht ml

24. Steroid Structures Cholesterol keeps fatty acid tails from sticking together  fluid mosaic model ring system of three cyclohexanes and one cyclopentane variety of functional groups that may be attached Large # of hydrocarbons = NONPOLAR Steroids cholesterol, estrogen, progesterone, testosterone, cortisone

28. Cholesterol

30. Building a prototype How do you start and what all do you need?

31. Protein production in cells DNA  nucleus double strand RNA  Leaves nucleus single strand Proteins ribosome amino acids

32. Protein Pathway 1.Nucleus- design 2.Ribosome-manufacturing in cytoplasm or on rough E.R. (endoplasmic reticulum) 3.Vesicles- transport protein to Golgi 4.Golgi- “address labels” modifies and packages 5.Vesicles- release proteins

33. WHAT ABOUT E? MITOCHONDRIA

34. Compare/Contrast: Mitochondria and ER

35. Cell Model: prokaryotic cell Cell wall Plasma membrane Cytoplasm Plasmid Ribosome Flagella And the FUNCTION of each!

36. Cell Model-Eukaryotic cell Plasma membrane Nucleus Nucleolus Nuclear envelope Mitochondria Ribosome Rough ER Smooth ER Golgi Apparatus Lysosomes Cytoplasm Chromatin Chromosomes Microtubules Microfilaments Animal cells need: centrioles Plants also need Cell wall Chloroplasts Vacuole MUST INCLUDE FUNCTION SOMEHOW

37. Notebook “Transport in cells” 1.Read article “The Theme of Membrane Transport in Cells” http://www.shmoop.com/biology- cells/membrane-transport.html http://www.shmoop.com/biology- cells/membrane-transport.html 2.Using gummy bears “cells”, digital scales, distilled water, sprite, sugar water, and salt water: test osmosis and diffusion in cells 3.Record in notebook including your research question, set up, data results, and analysis. 4.Expand: how can you make water move back out of your cells? How can sports drink companies use this type of experiment?
