  1. Monday and Tuesday8/19 and 8/20 • 1. Do Now • 2. Finish Graphic organizer (structure and function of organelles) • 3. Lab Safety • 4. Cell Project Info • 5. Break • 6. Notes-Plants vs. animal cells • 7. Study? • Homework: Study for function quiz on Wednesday 8/21

  2. Lab Safety

  3. 1. Listen to or read instructions carefully before attempting to do anything. 2. Wear safety goggles to protect your eyes from chemicals, heated materials, or things that might be able to shatter. 3. Notify your teacher if any spills or accidents occur. General Safety Rules

  4. 4. After handling chemicals, always wash your hands with soap and water. 5. During lab work, keep your hands away from your face. 6. Tie back long hair. General Safety Rules

  5. 7. Roll up loose sleeves. 8. Know the location of the fire extinguisher, fire blanket, eyewash station, and first aid kit. 9. Keep your work area uncluttered. Take to the lab station only what is necessary. General Safety Rules

  6. 10. It is suggested that you wear glasses rather than contact lenses. 11. Never put anything into your mouth during a lab experiment. 12. Clean up your lab area at the conclusion of the laboratory period. 13. Never “horse around” or play practical jokes in the laboratory. General Safety Rules

  7. 1. Chipped or cracked glassware should not be used. Show it to the teacher. 2. Broken glassware should not be disposed of in a classroom trashcan. There is a special glass disposal container for it. 3. When pouring liquids into glassware, make sure the container you are pouring into is resting on a table at least a hands breadth from the edge. Glassware Safety

  8. 4. Pour down a glass stirring rod to prevent liquids from splattering. 5. If a piece of glassware gets broken, do not try to clean it up by yourself. Notify the teacher. 6. When inserting glass tubing into a rubber stopper, apply a lubricant like glycerin to the glass and use a twisting motion. Glassware Safety

  9. 7. Do not place hot glassware in water. Rapid cooling may make it shatter. Glassware Safety

  10. 1. Wear protective goggles and a lab apron whenever heating or pouring hazardous chemicals. 2. Never mix chemicals together unless you are told to do so (and then only in the manner specified). 3. Never taste any chemicals (you should never taste anything in the lab). Chemical Safety

  11. 4. If you need to smell the odor of a chemical, waft the fumes toward your nose with one hand. Do not put your nose over the container and inhale the fumes. 5. Never pour water into a concentrated acid. Acid should be poured slowly into water. Chemical Safety

  12. 6. Follow the instructions of your teacher when disposing of all chemicals. 7. Wash your hands after handling hazardous chemicals. Chemical Safety

  13. 1. Lay electrical cords where no one can trip on them or get caught in them. 2. Be sure your hands and your lab area are dry before using electrical equipment. 3. Never poke anything into electrical outlets. Electrical Safety

  14. 4. Unplug cords by pulling the plug and not the cord. 5. Unplug all electrical equipment at the end of the lab period. Electrical Safety

  15. 1. Let burners and hotplates cool down before touching them. Test to see if they are cool enough by bringing the back of your hand close to them. 2. Use tongs and/or protective gloves to handle hot objects. 3. Never reach across an open flame or burner. Heating Safety

  16. 4. The only type of glassware that may safely be heated is either Kimax or Pyrex. 5. Always point the top ends of test tubes that are being heated away from people. 6. When heating a test tube, move it around slowly over the flame to distribute the heat evenly. Heating Safety

  17. 7. Only glassware that is thoroughly dry should be heated. 8. Heat glassware by placing it on a wire gauze platform on a ring stand. Do not hold it in your hand. Heating Safety

  18. 9. When lighting a burner, wait until the striker is in place before you turn on the gas. 10. The amount of air can be adjusted by the air supply valve below the tube of the burner. This regulates the flame temperature and color. 11. Never leave a burner or hotplate unattended. Heating Safety

  19. Injury: Burns What To Do: Immediately flush with cold water until burning sensation is lessened. First Aid

  20. Injury: Cuts, bruises What To Do: Do not touch an open wound without safety gloves. Pressing directly on minor cuts will stop bleeding in a few minutes. Apply cold compress to bruises to reduce swelling. First Aid

  21. Injury: Fainting To Do: Provide fresh air and have the person recline so that their head is lower than the rest of their body. First Aid

  22. Injury: Eyes What To Do: Flush eyes immediately with plenty of water for several minutes. If a foreign object is lodged in the eye, do not allow the eye to be rubbed. First Aid

  23. Injury: Poisoning What To Do: Find out what substance was responsible for the poisoning and alert the teacher immediately. First Aid

  24. Injury: Spills on the skin What To Do: Flush with large quantities of water. For acid spills, apply baking soda solution. For base spills, apply vinegar or boric acid. First Aid

  25. Injury: Electrical shock What To Do: Shut off the current at the source. Remove wire with rubber gloves. Alert the teacher immediately. First Aid

  27. Thurs/Friday 8-22 and 8-23 • 1. Do now • 2. Checkhomework (5L) • 3. CorrectQuizes • 4. Cell Project Questions • 5. Notes-Plant vs. Animalcells • 6. Break • 7-Graphic organizer – Respiration and Photosynthesis

  28. Cell Membrane • Separates the cell from the outside environment • Allows things to come in and out of cell • The “skin of the cell”

  29. Cytoplasm • Gel like fluid that moves all the organelles around the cell

  30. Cytoskeleton • Framework (looks like webs) that gives cell their shape • Important for animal cells

  31. Nucleus • Control center of the cell • Storage area for all the genetic information • Surrounded by nuclear envelop • The center of the nucleus is called the nucleolus ( where ribosomes are made)

  32. Ribosomes • Factories that produce proteins • Can be attached to endoplasmic reticulum or just float in cytoplasm

  33. Endoplasmic Reticulum • Passage way that helps carry material throughout the cell • Close to nucleus • Helps make proteins

  34. Golgi Bodies • Receive proteins and other materials from E.R. and distribute it to other parts of cell • “Delivery system of the cell” • Looks like a stack of plates

  35. Mitochondria • Rod shaped organelle (peanut) that converts food into usable energy

  36. Lysosomes • Have chemical that break down waste, large food particles, and old cell parts • “cells clean up crew” • Small round organelles (bigger than ribosomes)

  37. Vacuoles • Water filled sac that store food, waste, and other materials needed for the cell • Animal cells have small vacuoles • Plant cells have large “Central vacuoles”

  38. Chloroplasts • Capture energy from sunlight and use it as food for the cell • Make leaves green • Green structures

  39. Cell Walls • Protects and support the cell • Made of strong cellulose (makes plant rigid) • Gives plant cells their boxy appearance

  40. Large Central Vacuole • Plant cells have an enlarged central vacuole to hold a lot of water. • Helps give plants its shape

  41. Plant vs. Animal Cells 8/22/13/ 8/23/13 How are plant and animal cells the same? -Have 10 of the same organelles that function similarly -all need and have water - All need carbohydrates, lipids, proteins, nucleic acids 5R

  42. Plant vs. Animal Cells 8/22/13/ 8/23/13 How are plant and animal cells the same? Carbohydrates: cells use sugars and starches for energy Makes up structures like cell walls and cell membranes Lipids: fats oils and waxes that have more energy than carbs Makes up most of cell membrane 5R

  43. Plant vs. Animal Cells 8/22/13/ 8/23/13 How are plant and animal cells the same? Proteins: found in meat eggs fish nuts and beans Most of the organelles are made up of proteins. *Enzymes is a type of protein that speeds up chemical reactions. 5R

  44. Plant vs. Animal Cells 8/22/13/ 8/23/13 How are plant and animal cells the same? • Nucleic Acids: • DNA determines the job of the cell. • DNA is found in the nucleus. • RNA helps make proteins 5R

  45. Plant vs. Animal Cells 8/22/13/ 8/23/13 How are plant and animal cells different? Shape Organelles -Animal cells are round and plant cells are more boxy because of cell wall 5R

  46. Plant vs. Animal Cells 8/22/13/ 8/23/13 How are plant and animal cells different? -Plant cells have chloroplast to get food from sunlight, then the mitochondria converts this food into energy 5R

  47. Plant vs. Animal Cells 8/22/13/ 8/23/13 How are plant and animal cells different? Plant cells have a large central vacuole where they store water, giving them some structural support 5R

  48. Summary • How are animal and plant cells similar? • How are animal and plant cells different? Be specific!
