  • What are the two main stages of photosynthesis?
    The two main stages of photosynthesis are the light reactions and the Calvin cycle.
  • Where do the light reactions of photosynthesis occur?
    The light reactions occur inside the thylakoids of the chloroplast.
  • What are the primary reactants used in the light reactions?
    The primary reactants used in the light reactions are light (photons) and water.
  • What are the main products of the light reactions?
    The main products of the light reactions are oxygen gas and chemical energy (ATP and NADPH).
  • Where does the Calvin cycle take place within the chloroplast?
    The Calvin cycle takes place in the stroma of the chloroplast.
  • What does the Calvin cycle use to synthesize glucose?
    The Calvin cycle uses carbon dioxide from the atmosphere and chemical energy produced by the light reactions to synthesize glucose.
  • What is the role of chloroplasts in photosynthesis?
    Chloroplasts act as the site of photosynthesis, where both the light reactions and the Calvin cycle occur.
  • What are the overall inputs and outputs of photosynthesis?
    The inputs of photosynthesis are solar energy, water, and carbon dioxide, while the outputs are oxygen gas and glucose.
  • Which stage of photosynthesis is responsible for generating glucose?
    The Calvin cycle is responsible for generating glucose.
  • What is the significance of ATP in photosynthesis?
    ATP, produced during the light reactions, provides the chemical energy needed for the Calvin cycle to synthesize glucose.
  • How is oxygen gas produced during photosynthesis?
    Oxygen gas is produced during the light reactions when water molecules are split.
  • What is the role of NADPH in the Calvin cycle?
    NADPH provides the reducing power needed to convert carbon dioxide into glucose in the Calvin cycle.
  • What is the relationship between the light reactions and the Calvin cycle?
    The light reactions produce ATP and NADPH, which are then used by the Calvin cycle to synthesize glucose from carbon dioxide.
  • What is the primary function of the thylakoids in photosynthesis?
    The primary function of the thylakoids is to house the light reactions, where light energy is converted into chemical energy.
  • What is the significance of the stroma in the chloroplast?
    The stroma is the site of the Calvin cycle, where carbon dioxide is fixed into glucose using the energy from ATP and NADPH.
  • can you place the labels in this concept map that summarizes the stages of photosynthesis?
    The concept map for the stages of photosynthesis should include the following labels: 'Light Reactions' and 'Calvin Cycle'. The Light Reactions occur in the thylakoids and convert light energy and water into chemical energy and oxygen. The Calvin Cycle occurs in the stroma and uses carbon dioxide and the energy from the light reactions to synthesize glucose.
  • what are two other names for the light independent reactions?
    Two other names for the light-independent reactions are the 'Calvin Cycle' and the 'Dark Reactions'.
