Photosynthesis

• Photosynthesis


  The process that allows plants to grow and survive
• Photosynthesis


  1. Takes place in the leaves

  2. Takes place in chloroplasts

  3. Chlorophyll absorbs light energy

  4. Converts carbon dioxide and water into glucose and oxygen
• Photosynthesis is an endothermic reaction that requires light energy from the environment
• Obtaining reactants for photosynthesis

  1. Carbon dioxide diffuses into leaves through stomata

  2. Water is taken up from soil by roots and transported to leaves via xylem
• Glucose


  The main product of photosynthesis that plants use
• Uses of glucose by plants

  • Cellular respiration
  • Making cellulose
  • Making starch
  • Making amino acids
  • Making oils and fats
• Plant growth rate is often dependent on the rate of photosynthesis
• Factors that affect the rate of photosynthesis are light intensity, temperature, carbon dioxide concentration, and the amount of chlorophyll
