  1. Cells: TYPES, STRUCTURES, TRANSPORT, ENERGY, AND DIFFERENTIATION

  2. Prokaryote vs. Eukaryote Quick check: Create a Venn diagram comparing and contrasting prokaryotic and eukaryotic cells. Prokaryote Eukaryote

  3. Plant vs. Animal cell Animal Cell Plant Cell Quick Check: What organelles might a scientist see missing inside an animal cell that would be inside of a plant cell? Explain why these organelles are missing from the animal cell. Cell Song

  4. Microscopes • Quick check: What parts of the microscope are multiplied together to calculate the total magnification?

  5. Levels of organization Quick Check: Groups of ___________ form tissues, tissues form ______________, and ____________ form ___________ systems.

  6. Cell Transport Draw the u-tube after OSMOSIS. Quick Check: Choose which answer best describes the type of transport. Active transport: hi→lo or lo→hi uses energy or does not use energy Passive transport: : hi→lo or lo→hi uses energy or does not use energy Draw the beaker after DIFFUSION.

  7. Photosynthesis and cell respiration Quick Check: For PHOTOSYNTHESIS, label each reactant and each product. What organelle is this? Quick Check: For CELL RESPIRATION, label each reactant and each product. What organelle is this? Quick Check: How is anaerobic fermentation different from aerobic respiration? Photosynthesis Song

  8. Cell specialization Quick Check: Do all cells have the same DNA? What makes each cell in the picture look and function differently?

  9. 1.What will most likely be the result if all of the mitochondria are removed from a plant cell?  A. It will be unable to carry out respiration. B. It will lose water through osmosis. C. It will break down the ribosomes in the cell. D. It will be unable to photosynthesize. 2. What process best explains how a nerve cell and a muscle cell can both develop from the same fertilized egg?  A. differentiation B. natural selection C. selective breeding D. genetic engineering

  10. 3. How does the amount of energy resulting from fermentation compare with that of aerobic respiration? A. Aerobic respiration results in less energy. B. Aerobic respiration results in more energy. C. Each process results in equal amounts of energy. D. Each process results in variable amounts of energy  4. This diagram shows a plant cell. Which structure is found in a plant cell but is absent in an animal cell?  A. 1 B. 2 C. 3 D. 4

  11. 5. Which best explains why muscle cells are different from blood cells?  A. A mutation occurs during the development of muscle cells but not in blood cells. B. Different genes are activated in muscle cells than in blood cells. C. Muscles cells experience different environmental influences than blood cells. D. Muscle cells are produced by the brain, but blood cells are produced by the heart. 6. A freshwater plant is placed in a container of saltwater. What will most likely happen to the cells of the plant?  A. They will swell because water will move into them. B. They will swell because salt will move into them. C. They will shrink because water will move out of them. D. They will shrink because salt will move out of them.

  12. 7. If energy is needed to move materials into or out of a cell, what is most likely occurring?  A. active transport B. passive transport C. osmosis D. diffusion 8. How are prokaryotic and eukaryotic cells similar?  A. Both contain a nucleus. B. Both contain ribosomes. C. Both contain membrane-bound organelles. D. Both contain cell walls.

  13. 9. Which statement best compares aerobic and anaerobic respiration?  A. Less ATP is generated during anaerobic respiration than during aerobic respiration. B. More water is generated during anaerobic respiration than during aerobic respiration. C More oxygen is generated during an aerobic respiration than during aerobic respiration. D Less lactic acid is generated during anaerobic respiration than during aerobic respiration.

  14. 10. Which would be the best evidence that a cell is using active transport to move a substance across its cell membrane? A. Substances are moving rapidly across the cell membrane. B. ATP is being rapidly consumed near the cellular membrane. C. Substances are moving from high to low concentrations. D. Substances are moving through channels in the cell membrane.
