Answer:
B. To make more complex sugar molecules
D. To store energy for life processes
Step-by-step explanation:
Photosynthesis is a process that allows plants to use light energy from the sun to make sugar molecules. These molecules are used by the plant to build other compounds, such as proteins and lipids, that are essential for its growth and survival. The plant also stores some of the sugar as starch or other complex carbohydrates for future use. To perform photosynthesis, the plant needs carbon dioxide and water, which it obtains from the air and soil. The plant releases oxygen as a by-product of this process.
