Photosynthesis

• What is the process by which plants use light energy to produce glucose?

  Photosynthesis
• Why is photosynthesis considered an endothermic reaction?

  Because it absorbs energy from light
• What are the main components required for photosynthesis?

  • Light energy
  • Carbon dioxide
  • Water
• Where does photosynthesis take place in a plant?

  The leaves
• What is the role of chlorophyll in photosynthesis?

  Chlorophyll absorbs light energy
• What is produced as a byproduct of photosynthesis?

  Oxygen
• What are the word and chemical equations for photosynthesis?

  Word equation:

  • Carbon dioxide + Water → Glucose + Oxygen

  
  

  Chemical formulas:

  • Carbon dioxide: $CO_2$
  • Water: $H_2O$
  • Glucose: $C_6H_{12}O_6$
  • Oxygen: $O_2$
• What happens to the rate of photosynthesis when light intensity is increased?

  The rate of photosynthesis increases
• What does it indicate if the rate of photosynthesis levels off despite increasing light intensity?

  Another factor is limiting the process
• What is the effect of increasing carbon dioxide levels on the rate of photosynthesis?

  The rate of photosynthesis increases
• How does the amount of chlorophyll affect photosynthesis?

  It decreases the rate of photosynthesis
• How does temperature affect the enzymes involved in photosynthesis?

  It increases enzyme activity until denaturation occurs
• What are the factors that affect the rate of photosynthesis?

  • Light intensity
  • Carbon dioxide levels
  • Amount of chlorophyll
  • Temperature
