Photosynthesis

• Photosynthesis


  The process by which plants use light energy from the sun, carbon dioxide from the air, and water from the soil to produce glucose and oxygen
• Photosynthesis


  1. Light energy from the sun shines down onto the leaf

  2. Leaf takes in carbon dioxide from the air

  3. Leaf takes in water from the soil

  4. Leaf uses light energy, carbon dioxide, and water to produce glucose

  5. Leaf releases oxygen as a byproduct
• Photosynthesis


  1. Light from the sun shines down to the chloroplast

  2. Chlorophyll in the leaves takes in carbon dioxide and water

  3. Chlorophyll combines carbon dioxide and water to create glucose

  4. Glucose can be used for respiration, growth, and storage

  5. Oxygen is released into the atmosphere
• Word equation for photosynthesis

  Carbon dioxide + Water → Glucose + Oxygen
• Balanced symbol equation for photosynthesis

  6CO2 + 6H2O → C6H12O6 + 6O2
• The chlorophyll in the leaves does not take part in the photosynthesis reaction, it can be used over and over again
• Photosynthesis is an endothermic reaction, it takes in energy in the form of light
• Uses of glucose produced in photosynthesis

  • Respiration
  • Stored as starch
  • Used to make other substances (e.g. cellulose, proteins)
• Products of photosynthesis


  Used in respiration
• Products of respiration


  Used in photosynthesis
• Starch


  Insoluble form of glucose that can be stored by the plant when photosynthesis is not taking place
• Glucose produced in photosynthesis can also be transported as sucrose

• Word equation for photosynthesis

  Carbon dioxide + Water → Glucose + Oxygen
• Balanced symbol equation for photosynthesis

  6CO2 + 6H2O → C6H12O6 + 6O2
• The chlorophyll in the leaves does not get used up in the photosynthesis reaction, so it can be used over and over again
• Photosynthesis is an endothermic reaction, meaning it takes in energy in the form of light
• Uses of glucose produced in photosynthesis

  • Respiration
  • Stored as starch
  • Used to make other substances (e.g. cellulose, proteins)
• Products of photosynthesis


  Used in respiration

  Used in photosynthesis
• Starch


  An insoluble form of glucose that plants can store for later use
• Glucose produced in photosynthesis can also be transported as sucrose
