Photosynthesis

• What is the main product of photosynthesis?


  Glucose
• What are the reactants of the photosynthesis equation?


  Carbon dioxide and water
• What is the overall equation for photosynthesis?


  Carbon dioxide + water + light → glucose + oxygen
• What are the five main ways plants use glucose?


  1. For respiration
  2. Making cellulose
  3. Making amino acids
  4. Stored as oils or fats
  5. Stored as starch
• How do plants use glucose for respiration?


  It transfers energy from glucose, enabling the plant to convert glucose into various substances.
• What is cellulose made from?


  Glucose
• What role do nitrate ions play in plants?

  Nitrate ions are combined with glucose to make amino acids.
• What are lipids made from in plants?


  Glucose
• Why do plants store glucose as starch?


  Starch is insoluble, making it better for storage than glucose.
• What happens to a cell with lots of glucose in it?


  It would draw in loads of water and swell up.
• What does the term 'photosynthesis' mean?


  • 'Photo' means light
  • 'Synthesis' means putting together
  • Photosynthesis means putting together using light
• What is the significance of the term 'synthesis' in photosynthesis?


  It refers to the process of putting together substances using light.
• Why is it suggested to learn the photosynthesis equation instead of just the meaning of the term?


  Learning the equation provides a clear understanding of the process.
