photosynthesis

• What process do plants use to trap light energy?

  Photosynthesis
• What type of reaction is photosynthesis?

  Endothermic reaction
• Where does photosynthesis take place in a plant?

  In the leaves
• What chemical absorbs light energy in plants?

  Chlorophyll
• What are the inputs for photosynthesis?

  Carbon dioxide and water
• What is produced as a byproduct of photosynthesis?

  Oxygen
• What is the word equation for photosynthesis?

  Carbon dioxide + water → glucose + oxygen
• What is the formula for carbon dioxide?

  CO₂
• What is the formula for water?

  H₂O
• What is the formula for glucose?

  C₆H₁₂O₆
• What is the formula for oxygen?

  O₂
• What happens to the rate of photosynthesis when light intensity is increased?

  The rate of photosynthesis increases
• What does it mean if light intensity is a limiting factor?

  Photosynthesis is not as fast as possible
• What happens when light intensity is increased beyond a certain point?

  The rate of photosynthesis levels off
• What is the effect of increasing carbon dioxide levels on photosynthesis?

  The rate of photosynthesis increases
• What happens when carbon dioxide is no longer a limiting factor?

  The rate of photosynthesis levels off
• What factor can affect the rate of photosynthesis related to leaf composition?

  The amount of chlorophyll
• How does temperature affect the enzymes involved in photosynthesis?

  Higher temperatures increase enzyme activity
• What happens to enzymes at very high temperatures?

  They denature and activity falls
• What is the overall process of photosynthesis?

  1. Light energy is absorbed by chlorophyll
  2. Carbon dioxide and water are taken in
  3. Glucose and oxygen are produced
• What are the main factors affecting the rate of photosynthesis?

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