  4. 4. Making food• Green plants are the only living things which can make their own food.• This process is called photosynthesis. Copyright of www.makemegenius.com, for more videos ,visit us.
  5. 5. Making food• Leaves are green in colour because they contain chlorophyll.• Chlorophyll is needed in photosynthesis. Copyright of www.makemegenius.com, for more videos ,visit us.
  6. 6. What does the plant need ? For photosynthesis to take place a plant needs :• Carbon dioxide from the air• Light from the sun• Water from the rain• Chlorophyll from the leaves Copyright of www.makemegenius.com, for more videos ,visit us.
  7. 7. What then … ?• When the plant has all of these things … … photosynthesis can take place.• The plant produces sugar and oxygen. Copyright of www.makemegenius.com, for more videos ,visit us.

  9. 9. Photosynthesis in Overview• Process by which plants and other autotrophs store the energy of sunlight into sugars.• Requires sunlight, water, and carbon dioxide.• Overall equation: 6 CO2 + 6 H20  C6H12O6 + 6 O2• Occurs in the leaves of plants in organelles called chloroplasts.Copyright of www.makemegenius.com, for more videos ,visit us.
  10. 10. Leaf Structure• Most photosynthesis occurs in the palisade layer.• Gas exchange of CO2 and O2 occurs at openings called stomata surrounded by guard cells on the lower leaf surface. Palisade Spongy Copyright of www.makemegenius.com, for more videos ,visit us.
