2 Do Now: Explain which type of cell evolved first, the eukaryote or prokaryote!!!

3 Hmwk: Complete the worksheet on organelles handout pg4 Do now: Answer the following: 1. Who named the cell a “cell”? 2. What are the 2 types of cells used to category life? 3. What is one difference between the two?

4 7–1Life Is Cellular A. The Cell Theory 1. Cells are the units of structure and function of all organisms 2. All cells come from pre-existing cells B. Scientists 1. Robert Hooke C. 2 Types Cells 1. Prokaryotes: Archaea Bacteria and Eubacteria 2. Eukaryotes 1. Ex: WBC, skin cell, cheek cell, plant cell, stem cell Section 7-1 Go to Section:

31 Video Clip Questions: 1. What is the most outer layer of the animal cell? What can easily diffuse through this structure? 2. What is the meaning of the word organelle? 3. What does the nucleus function as? 4. What organelle produces protein? 5. What organelle turns oxygen and glucose to ATP/energy? 6. What organelle packages proteins with lipids and carbohydrates and places them into vesicles to be shipped out of the cell? 7. What organelle contains enzymes to digest particles and old organelles?

36 Outside of cell Inside of cell (cytoplasm) Cell membrane Proteins Protein channel Lipid bilayer Carbohydrate chains Section 7-3 Figure 7-15 The Structure of the Cell Membrane Go to Section: Cell Membrane

37 Transport: Movement Through the Membrane A.Cell Membrane is composed of? protein channel Carbohydrate chains Lipids 1. Function: Regulates what enters and leaves the cell: semi-permeable membrane Provides protection and support Cell identification Go to Section:

38 B. Transportation 1. Diffusion Movement of molecules from an area of high concentration to area of low concentration Movement occurs without any ATP Eventually looking for equilibrium, or stability 2. Passive Transport Movement of molecules across a membrane going along its concentration gradient Concentration gradient:  the amount of molecules in a certain area where there is movement from a highly concentrated area to a low concentrated area 07_11Diffusion_A.html

39 3. Osmosis Diffusion of water through a semi-permeable membrane from area of high concentration to low concentration Water will move across the membrane until equilibrium has been reached 4. Questions: Movement of Water 1. If high concentration of water molecules in the cell where will the water go? 2. If there is a low concentration of water molecules, where will the molecules go? 3. When equilibrium is reached is the concentration of the solution in the cell compared to outside of the cell different or the same? 07_11Diffusion_A.html perfume concentration gradient.gif 07_13Osmosis_A.html

40 Cell membrane Higher Concentration of Water Lower Concentration of Water Water molecules Sugar molecules Section 7-3 Figure 7-17 Osmosis Go to Section: What process is taking place here?

41 5. What is a solution? Solvent: solute: C. Types of Solutions Isotonic: The amount of solutes compared to the amount in a cell are equal to the amount outside the cell Hypertonic: The amount of solutes in the solution are high Hypotonic: Amount of solutes in a solution are low

42 Study and organize your BINDER!!!! Do Now: List and define the 3 types of solutions

43 Effect of Osmosis on a Cell

45 What is happening here? 07_13Plasmolysis_SV.mpg 07_13TurgidElodea_SV.mpg

46 Answer the following: 1. What is the preferred solution for a red blood cell? 2. What will happen to a red blood cell if you place it in distilled water? 3. What will happen to an animal cell if it were placed in a salt water solution? 4. What is the preferred solution for a plant cell? 5. Why can a red blood cell not live in the same type of solution as a plant ?

47 D. More Types of Transport A. Facilitated Diffusion If a molecule is too large to pass through the membrane, it needs assistance via protein channel. B. Active Transport Transport of material through the membrane with the use of ATP The molecules are going against the concentration gradient F:\biodoc.pp\powerpoints\videos&presentation\07_16ActiveTranspo rt_A.html 1. endocytosis ex: phagocytosis and pinocytosis F:\biodoc.pp\powerpoints\videos&presentation\07_20aPhagocytosis _A.html F:\biodoc.pp\powerpoints\videos&presentation\07_20bPinocytosis_ A.html 2. exocytosis 07_20_Exocytosis_A.html
