Questions and Answers
  • 1. 
    In what way are photosynthesis and cellular Is respiration similar?
    • A. 

      They both occur in chloroplasts.

    • B. 

      They both require sunlight.

    • C. 

      They both involve organic and inorganic molecules.

    • D. 

      They both require oxygen and produce carbon dioxide.

  • 2. 
    A student performed an experiment to demonstrate that a plant needs chlorophyll for photosynthesis. He used plants that had green leaves with white areas. After exposing the plants to sunlight, he removed a leaf from each plant and processed the leaves to remove the chlorophyll. He then tested each leaf for the presence of starch. Starch was found in the area of the leaf that was green, and no starch was found in the area of the leaf that was white. He concluded that chlorophyll is necessary for photosynthesis. Which statement represents an assumption the the student had to make in order to draw this conclusion?
    • A. 

      Starch is synthesized from the glucose produced in the green areas of the leaf.

    • B. 

      Starch is converted to chlorophyll in the green areas of the leaf.

    • C. 

      The white areas of the leaf do not have cells.

    • D. 

      The green areas of the leaf are heterotrophic.

  • 3. 
    The diagram below represents events associated with a biochemical process that occurs in some organisms.   Which statement concerning this process is correct?
    • A. 

      The process represented is respiration and the primary source of energy for the process is the Sun.

    • B. 

      The process represented is photosynthesis and the primary source of energy for the process is the Sun.

    • C. 

      Process converts energy in organic compounds into solar energy which is released into the atmosphere.

    • D. 

      This process uses solar energy to convert oxygen into carbon dioxide.

  • 4. 
    Decomposers are necessary in an ecosystem because they
    • A. 

      Produce food for plants by the process of photosynthesis

    • B. 

      Provide energy for plants by the process of decay

    • C. 

      Can rapidly reproduce and evolve

    • D. 

      Make inorganic materials available to plants

  • 5. 
    Which phrase, if placed in box X, would correctly complete the flowchart shown below?  
    • A. 

      Increased use of starch in root cells

    • B. 

      Increased concentration of glucose in leaf cells

    • C. 

      Decreased ATP in root cells

    • D. 

      Decreased concentration of oxygen in leaf cells

  • 6.

    • A. 

      Store information

    • B. 

      Build proteins

    • C. 

      Release energy from nutrients

    • D. 

      Dispose of metabolic wastes

  • 7. 
    Which substance is the most direct source of the the energy that an animal cell uses for the synthesis of materials?
    • A. 

      ATP

    • B. 

      Glucose

    • C. 

      DNA

    • D. 

      Starch

  • 8. 
    Which statement best describes these cells?
    • A. 

      Cell B lacks vacuoles while cell A has them.

    • B. 

      DNA would not be found in either cell A or cell B.

    • C. 

      Both cell A and cell B use energy released from ATP.

    • D. 

      Both cell A and cell B produce antibiotics.

  • 9. 
    Why is a mushroom considered a heterotroph?
    • A. 

      It manufactures its own food.

    • B. 

      It divides by mitosis.

    • C. 

      It transforms light energy into chemical energy.

    • D. 

      It obtains nutrients from its environment.

  • 10. 
    Which body system is correctly paired with its function?
    • A. 

      Excretory - produces antibodies to fight disease-causing organisms

    • B. 

      Digestive - produces hormones for storage and insulation

    • C. 

      Circulatory - transports materials for energy release in body cells

    • D.

      The process of respiration in the snail would decrease.

    • C. 

      The rate of reproduction of the fish would be affected.

    • D. 

      The organisms would probably survive because materials would cycle.
