  2. Energy in Cells

  3. Energy in Cells 1. What are the reactants of photosynthesis? • Water and glucose • Glucose and carbon dioxide • Carbon dioxide and water • Oxygen and water

  4. Energy in Cells 2. What is the source of energy for photosynthesis? • Sunlight • Glucose • Carbon dioxide • Water

  5. Energy in Cells 3. ADP must combine with which of the following in order to regenerate ATP? • A free phosphate • A positive ion • An adenine base • A molecule of glucose

  6. Energy in Cells 4. Glycolysis occurs in which part of the cell? • The thylakoid • The cytoplasm • The mitochondria • The cell membrane

  7. Energy in Cells 5. Which of the following traps light energy during the light reaction of photosynthesis? • Carbon dioxide • RNA • Chlorophyll • Water

  8. Comparing Organisms

  9. Comparing Organisms • A cladogram shows • Which kingdom is the most diverse. • How to name species. • Change over time. • Evolutionary relationships.

  10. Comparing Organisms 2. From earliest to most recent. Which is the correct order of subdivision? • protista, animalia, achaebacteria • Animalia, achaebacteria, protista • Achaebacteria, protista, animalia • Animalia, protista, achaebacteria

  11. Comparing Organisms 3. Eubacteria can be distinguished from archaebacteria by • The presence of a true nucleus • Being multicellular • Differences in RNA and makeup of the cell wall • The presence of membrane-bound organelles.

  12. 4. What do the similarities in the bones of a human arm and a whale’s flipper suggest? • Humans and whales share a common ancestor. • Humans evolved before whales. • Humans and whales can swim. • Arms are stronger than flippers.

  13. 5. Which organisms would be most closely related? • Organisms in the same kingdom. • Organisms in the same phylum. • Organisms in the same class. • Organisms in the same genus.

  14. Eukaryotes

  15. Eukaryotes • Which of the following shows the correct sequence in the anatomical levels of organization in humans? • organism, organ system, cell, organ, tissue • Cell, tissue, organ, organ system, organisms • Cell, organ, organ system, tissue, organism • Organisms, cell, organ, tissue, organ system

  16. Eukaryotes 2. An organism is multicellular and made up of eukaryotic cells. The organism can move from one place to another. Its cells do not have cell walls or chloroplasts. Where should the organism be classified? • Protista • Fungi • Plantae • Animalia

  17. Eukaryotes 3. Scientists once classified fungi as plants. Which of the following best explains why fungi are now classified in their own kingdom? • Fungus cells have cell walls, but plants cells do not. • The cells of fungi and plants both have nuclei and cell membranes. • Fungi are capable of independent movement, but plants are not. • Fungi do not have chloroplasts and cannot carry out photosynthesis like plants.

  18. Prokaryotes

  19. Prokaryotes • Which characteristic is most important in identifying a cell as prokaryotes? • The presence of a cell wall • The small size of the cell • The absence of a nucleus • Its existence as a unicellular organism

  20. Prokaryotes 2. What is one important way that archaebacteria are different from true bacteria? • Archaebacteria lack cell walls. • Archaebacteria are multicellular. • Archaebacteria lack cells with a nucleus. • Archaebacteria have different genetic material.

  21. Prokaryotes 3. Which of the following are not found in prokaryotic organisms? • Cell membrane • Cytoplasm • Nucleus • Membrane-bound organelles

  22. Viruses and Living Things

  23. Viruses and Living Things • Why are viruses not considered living things? • Viruses are not made of cells. • Viruses do not contain hereditary material. • Viruses cannot make their own nutrients. • Viruses can only be seen with an electron microscope.

  24. Viruses and Living Things 2. What determines the shape of a virus? • Its DNA • Its RNA • The presence of an envelope • The proteins in its capsid

  25. Viruses and Living Things 3. Which of these characteristics of both viruses and living organisms? • They get energy from their environment. • They contain proteins and nucleic acids. • They can reproduce on their own. • They can form crystals and remain dormant for long periods.
