Photoysnthesis

• Carbon


  • Water
  • Glucose
• Photosynthesis


  A chemical reaction that takes place in green plants
• Chloroplasts


  Controlled by enzymes
• Glucose


  • Used for respiration
  • Converted into cellulose to build cell walls
  • Converted into insoluble starch for storage
• Limiting factors of photosynthesis are temperature, light, and carbon dioxide
• Extracting leaf


  1. Cut leaf from plant using forceps

  2. Turn off Bunsen burner

  3. Place leaf in boiling water for 5 mins

  4. Remove leaf and wash with cold water to make it less fragile

  5. Spread leaf on white tile and add a drops of iodine
• Limiting factor


  Something that can affect the rate of photosynthesis
• As light intensity increases


  The speed of photosynthesis increases
• As carbon dioxide increases

  Photosynthesis increases
• As temperature increases


  The speed of photosynthesis increases
• When temperature reaches optimum


  Enzymes denature
• Glucose


  A byproduct of photosynthesis
• Root hair cells


  • Provide a large surface area to take in water from soil
• Palisade cells


  • Have many chloroplasts and absorb sunlight
• Chlorophyll


  Green pigment that absorbs sunlight
• Cellulose


  Carbohydrate that makes up cell walls
