Measure Photosynthesis with Floating Leaves STEM …
WebFloating Leaf Disk Photosynthesis Lab. Introduction: Photosynthesis is a process that converts carbon dioxide into sugars such as glucose using energy from the sun. When light is absorbed by pigments in a leaf, the energy absorbed is used to incorporate the carbon dioxide into organic molecules in a process called carbon fixation. http://berwicksclasses.org/AP%20Biology/Biology%20Assignments/AP%20BIOLOGY%20Lab%204.htm WebIn this lab, students explore the process of photosynthesis in spinach leaves.
