  4. Photosynthesis100 • In what organelle does photosynthesis take place?

  5. Photosynthesis200 • A cat eats a bird, which earlier ate a caterpillar that chewed on a weed. Which organisms are autotrophs? Heterotrophs?

  6. Photosynthesis300 • What is the equation for photosynthesis?

  7. Photosynthesis400 • CRITICAL THINKING: Suppose a garden in your neighborhood is filled with red, white, and blue petunias. Explain the floral colors in terms of which wavelengths of light they are absorbing reflecting.

  8. Photosynthesis1000 • Explain the chemiosmotic model of photosynthesis.

  9. Photosynthesis100-Answer • Photosynthesis takes place in the chloroplast.

  10. Photosynthesis200-Answer • The weed is the autotroph. The cat, bird, and caterpillar are heterotrophs.

  11. Photosynthesis300-Answer • 12 water + 6 carbon dioxide in the presence of light yields 6 oxygen + glucose + 6 water

  12. Photosynthesis400-Answer • White reflects all wavelengths. Red absorbs all wavelengths except for around 700. Blue absorbs all wavelengths except for around 450.

  13. Photosynthesis1000-Answer • Pigments absorb light enery and electrons bounce around until they reach the primary electron acceptor. Electrons are supercharged and shoot up, before they can fall down they are passed to the electron transport chain. As the electrons pass through the ETC, energy is given off and the energy is used to move hydrogen across the membrane into the inside. This creates an electrical gradient. The hydrogens wish to leave and can do so with the help of ATP synthase. ATP synthase binds a phosphate to ADP, creating ATP. • 100 Point Bonus: What is the difference between cyclic and noncyclicphosphorylation?

  14. Cellular Respiration100 • TRUE OF FALSE: Aerobic respiration occurs in animals but not plants, which make ATP only by photosynthesis.

  15. Cellular Respiration200 • What is the equation for aerobic respiration? Type question here

  16. Cellular Respiration300 • What forms during glycolysis? (3 things…)

  17. Cellular Respiration400 • What is cellular respiration? What would occur if there was no oxygen, what are the two types of alternative?

  18. Cellular Respiration1000 • Explain and illustrate the process cellular respiration.

  19. Cellular Respiration100-Answer • False.

  20. Cellular Respiration200-Answer • Write out: (HINT: Write photosynthesis backwards)

  21. Cellular Respiration 300-Answer • NADH • Pyruvate • ATP

  22. Cellular Respiration400-Answer • Cellular respiration is the process that releases energy by breaking down glucose and other food molecules in the presence of oxygen. Without the presence of oxygen, fermentation would occur. Lactaid acid or alcoholic fermentation.

  23. Cellular Respiration1000-Answer • Illustrate and explain.

  24. Cell Cycle/Mitosis100 • What does haploid and diploid mean?

  25. Cell Cycle/Mitosis200 • What are the two types of reproduction? How are they different?

  26. Cell Cycle/Mitosis300 • Why do cells divide? (3 things…)

  27. Cell Cycle/Mitosis400 • Why would you not expect to see a two-ton cell on the sidewalk?

  28. Cell Cycle/Mitosis1000 • What are the phases of cell cycle? Of mitosis? Explain each stage.

  29. Cell Cycle/Mitosis100-Answer • Haploid means one set of chromosomes. Diploid means two sets of chromosomes.

  30. Cell Cycle/Mitosis200-Answer • The two types of reproduction are sexual and asexual. In sexual reproduction, the offspring are genetically different from its parents. In asexual reproduction, the offspring is genetically identical to its parent.

  31. Cell Cycle/Mitosis300-Answer • Cells divide due to growth, repair, and reproduction.

  32. Cell Cycle/Mitosis400-Answer • Cell growth is restricted by volume-to-surface area ratio. The needs of the cell increase faster than the ability to meet those needs. The cell cannot expel waste fast enough. As a result of growth restriction, the cell divides.

  33. Cell Cycle/Mitosis1000-Answer • The stages of the cell cycle are G1, S, G2, and M phases. G1 is the first gap phase where the cell grows. In S phase, chromosomes are duplicated. During G2, organelles are duplicated. M phase stands for mitosis and cytokinesis. The stages of M phase are prophase, metaphase, anaphase, and telophase. During prophase, chromatins condense and the nuclear envelope breaks down. During metaphase, chromosomes line up across the cellular equator. During anaphase, sister chromatids break apart and gather at opposite spindle poles. During telophase, the nuclear envelope reforms.

  34. Meisosis100 • What is the name for chromosomes 1-22 (All chromosomes other than sex chromosomes).

  35. Meisosis200 • How do chromosomes line up during metaphase I of meiosis? What is this formation called?

  36. Meisosis300 • Sexual reproduction requires… (3 things)

  37. Meisosis400 • Why is meiosis important?

  38. Meisosis1000

  39. Meisosis100-Answer • They are called autosomes.

  40. Meisosis200-Answer • Chromosomes line up with their sister chromatids and homologous pairs. This is called a tetrad.

  41. Meisosis300-Answer • Sexual reproduction requires meiosis, gamete formation, and fertilization.

  42. Meisosis400-Answer • Meiosis allows for genetic diversity and helps to keep a constant number of chromosomes between generations.
