Objective: You will be able to differentiate between living and nonliving things.

1. Objective:You will be able to differentiate between living and nonliving things. Do Now: • Open your notebook to the inside cover • Write the following: • Living Environment midterm: Tuesday, January 24th @ 10:53 • May need to take the morning bus!

2. Life Characteristics

3. Characteristics of living things • All living things must perform certain functions to stay alive • Non living things do not do all of these • What activities can you think of?

4. Life Functions • Nutrition • Obtain and breakdown nutrients • Cell Respiration • Breakdown food to release energy • Transport • Moving things throughout itself • Synthesis • Combine simple substances • Growth • Reproduce • Regulation • Respond to the environment • Excretion • Ridding itself of waste • Response • React to internal or external stimuli

5. Life Characteristics • Homeostasis • Maintain a stable internal environment • Metabolism • All of the chemical reactions in the organism • Cells • All organisms are made up of at least one cell

6. Living things and cells • All living things are made up of one or more cells • Cells are the functional unit of living things • Some organisms have only one cell and are called unicellular • Some are even made up of trillions of cells

8. Do you smell what the Rock’s cooking?

9. Organization levels • Biologists break life down into different levels • This makes it easier to study life • The order from smallest to largest • Cells, tissues, organs, organ systems and organism

10. Cells make up living things

11. Tissues are groups of cells that work together

12. Organs are made of tissues working together

13. Organ systems are made of organs that work together

14. Organism is made of a group of organ systems working together

15. Objective: You will be able to give the function of each cell organelle. Do Now: • Read, “Nucleus” on p. 176 • What is chromatin made of?

18. Objective: You will be able to connect life functions to one or more cell organelles. Do Now: • Begin filling the function of any organelle you can remember • Circle the three that are the most difficult for you to remember • Place a star next to the organelle that you think is the most important

19. Activity • Look through your definitions for life functions. • List a life function and the organelle(s) that best match up with that life function • Write a sentence why the two go together • Ex. Transport -

20. Differences Between Animal and Plant Cells • Animal cells are round and plant cells are rectangular • Animal cells have lysosomes and centrioles • Animal cells have small vacuoles and plant cells have one large vacuole • Plant cells have chloroplasts and a cell wall

21. Cork Cells

22. Human Cheek Cells

23. Nucleus Onion Cells Nucleolus

24. Elodea Cell

25. Blood Cells

26. Objective:You will be able to differentiate between passive and active transport. Do Now: List two differences between active and passive transport

27. Outside of cell Carbohydrate chains Proteins Cell membrane Inside of cell (cytoplasm) Protein channel Lipid bilayer Figure 7-12 The Structure of the Cell Membrane Section 7-3

28. Molecule to be carried Energy Molecule being carried Figure 7-19 Active Transport Section 7-3

31. Figure 8.17 An electrogenic pump

32. Figure 8.15 The sodium-potassium pump: a specific case of active transport

33. Receptor

34. Objective:You will be able to compare and contrast the photosynthesis and respiration equations. Do Now: • Write the equations for both respiration and photosynthesis. • In a sentence write what happens to oxygen in each equation. • In a sentence write what happens to carbon dioxide in each equation.

35. Photosynthesis Equation 6CO2 + 6H2O C6H12O6 + 6O2 Carbon + Water Glucose + Oxygen Dioxide

36. Respiration Equation How can you remember the equation for respiration? C6H12O6 + 6O2 6CO2 + 6H2O + ATP

37. Chloroplasts Chloroplasts is the site of photosynthesis • Take in CO2 and Water to make glucose • Has green pigment called chlorophyll to capture sunlight • Gives of Oxygen as a waste

38. VS.

40. Global Warming • Is partly caused by an increase of CO2 in the air? • Why would cutting down a forest and leaving the trees to rot increase the effect of global warming?

41. Objective: You will be able to describe the structure and function of carbohydrates Do Now: • Read “Macromolecules” on p. 45 • Differentiate between monomers and polymers

42. Inorganic versus Organic compounds

43. An Element in the Periodic Table Section 2-1 6 1 H C + Carbon Hydrogen

44. Types of Organic Compounds • Carbohydrates • Lipids • Proteins • Nucleic Acids

49. Figure 5.2 The synthesis and breakdown of polymers

50. Carbohydrates Functions • Readily available source of energy • Energy storage • Strong building materials
