limiting factors

• What is the equation for photosynthesis?

  Light energy is absorbed by chlorophyll to react carbon dioxide with water to make glucose and oxygen.
• What happens to the rate of photosynthesis when light intensity is increased?

  The rate of photosynthesis initially increases as light intensity increases.
• What does it indicate if the rate of photosynthesis stops increasing despite further increases in light intensity?

  It indicates that light intensity is no longer the limiting factor.
• What are the three other factors that can limit photosynthesis?

  Carbon dioxide concentration, temperature, and the amount of chlorophyll in the leaves.
• How does increasing carbon dioxide concentration affect the rate of photosynthesis?

  Increasing carbon dioxide concentration increases the rate of photosynthesis until it is no longer the limiting factor.
• What happens when carbon dioxide concentration is increased beyond a certain point?

  The rate of photosynthesis does not change because there is plenty of carbon dioxide available.
• What effect does increasing temperature have on the rate of photosynthesis?

  Increasing temperature can increase the rate of photosynthesis until enzymes start to denature.
• What happens to enzymes in the leaf if the temperature is increased too much?

  The enzymes will start to denature, causing the rate of photosynthesis to fall.
• What are the limiting factors that can affect the rate of photosynthesis?

  • Light intensity
  • Carbon dioxide concentration
  • Temperature
  • Amount of chlorophyll in the leaves
• How do greenhouses help increase the rate of photosynthesis?

  Greenhouses provide light, heat, and extra carbon dioxide to increase the rate of photosynthesis.
• Why do farmers use greenhouses?

  Farmers use greenhouses to increase the yield of crops by enhancing the rate of photosynthesis.
• What is a potential problem with using greenhouses to increase photosynthesis?

  It can be expensive to maintain the conditions needed for increased photosynthesis.
• How do oil burners contribute to the greenhouse effect for plants?

  Oil burners release heat and carbon dioxide simultaneously, aiding in photosynthesis.
• Where can students find questions on limiting factors in photosynthesis?

  In the vision workbook linked in the video.
• What should students be able to do after watching the video on photosynthesis?

  Interpret graphs to determine the limiting factor in photosynthesis and explain how greenhouses are used to increase the rate of photosynthesis.
