| Q. |
The source of oxygen generated during photosynthesis is: |
| A. | water |
| B. | carbon dioxide |
| C. | chlorophyll |
| D. | mesophyll cells |
| Answer» A. water | |
|
Explanation: The source of oxygen produced during photosynthesis is the splitting of water molecule into hydrogen and oxygen. Photosynthesis uses carbon dioxide and water, releasing oxygen as a waste product. Although photosynthesis can happen in different ways in different species, some features are always the same. For example, the process always begins when energy from light is absorbed by proteins called photosynthetic reaction centers that contain chlorophylls. In plants, these proteins are held inside organelles called chloroplasts, while in bacteria they are embedded in the plasma membrane. |
