Photosynthesis

• Photosynthesis


  The process by which plants use sunlight, water and carbon dioxide to create oxygen and energy in the form of sugar
• Photosynthesis


  • It is an endothermic reaction
  • Energy from sunlight is absorbed by chlorophyll in chloroplasts
  • Plants use this energy to make the carbohydrate glucose from carbon dioxide and water
  • Oxygen is made and released as a waste product
• Photosynthesis can be defined as the process by which plants use sunlight, water and carbon dioxide to create oxygen and energy in the form of sugar
• Photosynthesis


  The process by which plants manufacture carbohydrates from raw materials using energy from light
• Photosynthesis


  • It is an endothermic reaction
  • Energy from sunlight is absorbed by chlorophyll, a green pigment found inside chloroplasts
  • Green plants use this energy to make the carbohydrate glucose from the raw materials carbon dioxide and water
  • Oxygen is made and released as a waste product
• Autotrophs


  Organisms that can make complex molecules (glucose) from simple molecules (carbon dioxide and water)
• Products of photosynthesis


  • Glucose (source of energy for respiration)
  • Starch (for storage)
  • Lipids (for energy source in seeds)
  • Cellulose (to make cell walls)
  • Amino acids (used to make proteins)
• The raw materials required for photosynthesis are carbon dioxide and water
