SAT English Practice Question

The process of photosynthesis begins when light energy is captured by chlorophyll, a green pigment found in plants. Chlorophyll absorbs light, which is then used to convert carbon dioxide and water into glucose and oxygen. This process is essential for life on Earth, as it provides the food and oxygen that all living things need. What role does chlorophyll play in the process of photosynthesis?

1. A.Chlorophyll, a green pigment found in plants, absorbs light, which is then used to convert carbon dioxide and water into glucose and oxygen.
2. B.Chlorophyll absorbing light, which is then used to convert carbon dioxide and water into glucose and oxygen.
3. C.Chlorophyll, a green pigment found in plants, absorbing light, which is then used to convert carbon dioxide and water into glucose and oxygen.
4. D.Chlorophyll—a green pigment found in plants—absorbs light, which is then used to convert carbon dioxide and water into glucose and oxygen.
