Leaf Structure and Photosynthesis Standard Grade Biology Photosynthesis • Green plants (producers) can use light energy to make their own food • This process is called photosynthesis • Green plants are green because they contain a chemical called chlorophyll. This chemical is used to trap light energy. • Chlorophyll is contained in the chloroplasts of plant cells • Light energy is used to change carbon dioxide and water into starch and oxygen • The word equation for photosynthesis is carbon + water dioxide Light energy starch + oxygen Structure of a leaf Starch Test a Leaf This powerpoint was kindly donated to www.worldofteaching.com http://www.worldofteaching.com is home to over a thousand powerpoints submitted by teachers.
