MICROSCOPE - Use the cards to help identify the parts of the compound light microscope. Eyepiece (ocular) Body Tube Nose piece Objectives Arm Stage Stage clips Diaphragm (Iris) Coarse adjustment knob Fine adjustment knob Light Base Problems: 1. 400 2. 100 CELL THEORY - Match the names of the scientist on your answer sheet to their contribution of the cell theory. a) First to identify and name the cell. 1. Leeuwenhoek b) Cells come from other cells. 2. Hooke c) Improved the microscope. 3. Schleiden d) All animals are made of cells. 4. Schwann e) All plants are made of cells. 5. Virchow PROKARYOTIC VS. EUKARYOTIC CELLS – Use the pictures of the cells on the review sheet to list the differences between eukaryotes and prokaryotes and identify the types of organisms that have these cells. 1. Eukaryotic cells have a nucleus and membrane bound organelles; prokaryotic cells do not. 2. bacteria 3. protists, plants, animals, and fungi Smooth ER Central vacuole nucleolus nucleus Cell membrane mitochondrion cytoskeleton Rough ER flagellum Rough ER Ribosomes Nuclear membrane PARTS OF AN ANIMAL AND PLANT CELLS - Use the cards to help identify the parts of the cell in the diagram. Golgi body Mitochondrion Cell wall Cell membrane Smooth ER Lysosome Cytoskeleton Golgi body Cytoskeleton Chloroplast ribosome Nuclear membrane nucleus nucleolus FUNCTION OF CELL ORGANELLES - Match the names of the cell organelles on your review sheet to their functions. 1.

G CELL MEMBRANE – Use the cards to help identify the parts of the cell membranes in the diagram. carbohydrates Nonpolar tails of phospholipids Bilayer of phospholipids Channel proteins steroids Polar heads of phospholipids Matching – match the description to the part of the cell membrane. 1. A 2. D 3. B 4. C CELL TRANSPORT – Fill in. There are two types of cell transport: active and passive. Passive transport does not require energy. This type of transport goes down the concentration gradient. Types includes diffusion (the movement of particles from high concentration to low concentration), osmosis (the movement of water from areas of low solute concentration to areas of high solute concentration), and facilitated diffusion (diffusion of larger molecules through protein channels. Active transport requires energy. This type of transport goes up the concentration gradient. Types include protein (ion) pumps (special protein pumps that move molecules against the gradient), endocytosis (process where cell surround large molecules with cell membrane and bring it into the cell), and exocytosis (process where cells excrete large particles out of the cell by fusing vesicles with the cell membrane). Problems – Read the problems for each picture and follow the instructions. 1. Use arrows to indicate the direction of diffusion. 2. Below are animal cells placed in beakers of various concentrations. Hypertonic Hypotonic Isotonic ENERGY IN THE CELL – Use the diagram on the lab sheet to answer the following questions. 1. Adenosine triphosphate 2. Adenosine diphosphate 3. ATP is a fully charged battery. When energy is extracted one of the phosphates come off and it becomes a half charged ADP. It can be recharged by adding a phosphate back on. PHOTOSYNTHESIS - Use the diagram to answer the questions on your answer sheet. 1. 6CO2 + 6H20 -> 6O2 + C6H12O6 2. Chloroplast 3. Thylakoid membrane 4. Light and water 5. NADPH to dark cycle 6. Stroma 7. NADPH and carbon dioxide 8. Glucose CELLULAR RESPIRATION – Use the diagrams on the lab sheet to answer the questions below. 1. C6H12O6 + 6 O2 -> 6CO2 + 6 H2O 2. Cytoplasm 3. Glucose and 2 ATP 4. 4 ATP, NADH and 2 pyruvate molecules 5. Oxygen 6. Matrix of the mitochondrion 7. 2 pyruvate molecules 8. Carbon dioxide, 2 ATP each molecule, and NADH 9. Cristae (inner membrane) of mitochondrion 10. NADH and oxygen 11. 32 ATP and water 12. ETC 13. Fermentation / anaerobic 14. The products of photosynthesis are the reactants of cellular respiration and vice versa. 15. Yes
