  1. Tuesday, January 15, 2013 Wednesday, January 16, 2013 Tuesday, January 15, 2013 Wednesday, January 16, 2013 “Practice Scenarios” Cell Transport Cell – the basic unit of all life Semi-permeable – some objects can pass through cell membrane (mostly water) Basic Cell Organelles: Cell Membrane – protects cell/gatekeeper Cytoplasm – fluid inside cell/ helps keep shape Nucleus – typically holds cells genetic material Prokaryotic vs. Eukaryotic Organisms Prokaryotic –single-celled organisms, no nucleus - usually bacteria, not very complex Eukaryotic – multi-cellular organisms, nucleus - usually more complex with more organelles Movement Into and Out of Cells: Diffusion: movement from an area of high concentration to low concentration Osmosis: diffusion of water across a semi-permeable membrane Warm Up: List the three points of the cell theory from your homework last night. Describe the difference between unicellular and multicellular organisms. Homework: Complete the “practice” found on the last notebook page for today Page 81 Page 82

  2. Using Energy to Transport Materials Across the Cell Membrane Two Main Categories: Passive Transport/Diffusion (usually small particles) – Moves substances from areas of high concentration to areas of low concentration Example: Food coloring added to a beaker of water: beforeafter Active Transport (usually larger particles) – Relies on the cell using energy (ATP) to move particles across the membrane Three Categories: 1. Transport Proteins: Special proteins use energy/ATP to pump materials into cell (gatekeeper) 2. Endocytosis: membrane surrounds particles to move them inside (see diagram on next slide) 3. Exocytosis : release of substances from inside vesicles through joining and then releasing from the cell membrane (see diagram on next slide)

  3. Exchanging materials between the cell and its environment Passive Transport Active Transport Transport Proteins use ATP Diffusion Endocytosis (reverse for Exocytosis) Osmosis

  4. Video’s and Examples Passive and Active Transport Animations Endocytosis and Exocytosis Animation

  5. Homework/Practice DIRECTIONS- First Identify if the process is moving materials by active or passive transport. Then determine if the process is diffusion, osmosis, transport proteins, endocytosis, or exocytosis. 1. WATER MOVES OUT OF PLANT LEAF, CAUSING IT TO WILT AND DRY. 2. IF YOU PLACE A TEA BAG IN WATER AND TEA IS MADE. 3. IF FOOD THAT IS TOO LARGE TO ENTER THROUGH THE CELL MEMBRANE IS BROUGHT INTO THE CELL TO KEEP IT FROM DYING. 4. YOU SMELL THE DELICIOUS ODOR OF BAKING COOKIES BEFORE YOU ENTER THE KITCHEN. 5. FRESH WATER MOVES INTO A SINGLE CELLED ORGANISM. 6. A ONE CELLED AMEOBA SURROUNDS A PARTICLE OF FOOD. 7. EXCESS SALT THAT AN IGUANA HAS SOAKED UP IN THE OCEAN IS REMOVED THROUGH THE NOSTRILS. 8. IF A PLANT PUMPS MINERALS FROM THE SOIL TO THE ROOT OF THE PLANT.

Provide examples. Why is it effective to divide the labor in this way? Organelle: – parts of a cell with specific function – structure in the cytoplasm of eukaryotic cell that can act as a storage site, process energy, move materials, or manufacture substances Mini-web quest using www.cellsalive.comwww.biology4kids.com Homework: Create chart of cell organelles and their functions Tell whether the part is in plant, animal, or both cells Page 83 Page 84

  8. Wednesday, January 23, 2013 Thursday, January 24, 2013 Wednesday, January 23, 2013 Thursday, January 24, 2013 Cell Organelle Quiz and Cell Cycle Notes Warm Up: Cell cycle - normal sequence of the development and division of a cell Three main stages: 1) Interphase - cell is performing normal functions and preparing to divide - the longest part of the cycle - cell grows about twice its original size - goes about regular cell activities - DNA is copied to prepare for mitosis 2) Mitosis- nucleus splits and divides - prokaryotes do not do this(no nucleus) - usually the shortest period in cycle - goal of mitosis is to transfer DNA and other cell structures from parent cell to new cell 3) Cytokinesis – occurs directly after mitosis - parent cell pinches off - two genetically identical cells form Homework: Page 85 Page 86

Thursday, January 31 , 2013 Friday, February 1, 2013 Thursday, January 31 , 2013 Friday, February 1, 2013 Food, Exercise, and Energy Project Study for Cell Test and Finish Study Guide calorie - with a lowercase “c,” the term refers to the amount of energy needed to raise the temperature of one gram of water one degree Celsius. Context: When it comes to staying healthy, counting calories is just one aspect. Calorie - with an uppercase “C,” the term refers to the amount of energy required to raise one kilogram of water (about 2.2 pounds) one degree Celsius; one Calorie, or kcal, is equal to 1,000 calories. Context: Nutrition is measured in Calories. diet - everything that is consumed. A balanced diet is based on the principle that healthful foods and appropriate nutrients must be consumed each day Context: Eating a healthful diet helps prevent high cholesterol, high blood pressure, heart disease, and many other health problems. Food Guide Pyramid - a visual representation of the number of recommended daily servings in each of the six food groups; designed by the U.S. Department of Agriculture Context: Use the Food Guide Pyramid as a general guide to help you choose a healthful diet. nutrients - substances, including proteins, carbohydrates, vitamins, and minerals, found in foods that are necessary for good health Context: Teenagers need to consume a great deal of calcium, the nutrient that helps build strong bones and teeth.

  18. -Microbiology is the study of “very small” organisms-many not visible with the “unaided eye”-many can cause disease and affect functions- explores bacteria, protists, some fungi, some parasites, and viruses

  19. Bacteria Characterisics Reproduction Binary fission • Simplest kind of life known • Found everywhere • Prokaryotes (DNA not stored in nucleus)

  20. Bacteria 3 main shapes • Spiral (also known as Spirillum) • Rod (Bacillus) • Round (Coccus) E. Coli – Causes food poisoning Streptococcus – causes strep throat Most spirilla affect animals

  21. Protists Plant-like Protist called Volvox Characteristics • Usually single-celled • moist environment • Grouped by how they move and get food Animal-like Protist called Paramecium Animal-like Protist called Amoeba Plant-like Euglena

  22. Protists Flagellates Psudopodia Move with false feet called psudopods Disease causer –Ameoba causing Dysentery Ciliates • Move with a whip like tail called flagella • Euglena • Plant-like • Move with tiny hairs called cilia • Cilia help capture food • Paramecium feeding (animal-like)

  23. Fungi Characteristics • 3 groups: mushrooms, molds, yeasts • Act as decomposers and absorbs nutrients Reproduction Mostly asexual Mostly with spore dispersal

  24. Fungi Good Examples Disease Causing Athlete’s Foot is a parasitic fungal infection caused by causes scaling, flaking, and itch of affected areas • Food • Yeast is used to make bread • Penicillin kills bacteria

  25. Parasites Characteristics • a harmful relationship to the host Reproduction • depends on the parasite

  26. Parasites Good Examples Disease Causing Tapeworms - from uncooked meat Fleas Bed bugs - suck blood from sleeping victims • Harmful by definition

  27. VIRUSES Characteristics • Smaller than bacteria • NOTliving organisms • Consist of genetic material within a special protein coating called a capsid.

  28. VIRUSES Reproduction • Use host cell to copy DNA and produce new viruses • 5 steps to virus multiplication: • Attachment • Injection • Production • Assembly • Release

  29. VIRUSES Helpful Virus Examples Bad Examples West Nile virus Influenza • Used to transfer helpful genes into cells – gene therapy
