Explanation:

1. Photosynthesis is the process by which cells capture solar - energy and convert it into food.
2. In photosynthesis, plants convert carbon dioxide and water into oxygen and glucose.
3. Photosynthesis occurs in the chloroplast.
4. Chlorophyll gives plants their green color.
5. Sunlight is the energy source for photosynthesis.
6. The light - dependent reaction occurs in the thylakoid of the chloroplast.
7. Glucose is not a reactant of the light - dependent reaction.
8. Oxygen is not required for photosynthesis to occur.
9. The oxygen released during photosynthesis comes from water.
10. The sugar made during photosynthesis is stored for later use.
11. The light - independent reaction does not require light, so the statement that it requires light is false.
12. Photosynthesis takes place primarily in plants.
