Question

what type of molecule do chloroplasts create for energy use by the cell?
sugars
fatty acids
proteins

Explanation:

Chloroplasts are the site of photosynthesis. In photosynthesis, plants use sunlight, carbon dioxide ($CO_2$) and water ($H_2O$) to produce glucose (a type of sugar) and oxygen ($O_2$). Glucose is a key energy - providing molecule for the cell. Fatty acids are mainly involved in lipid synthesis and energy storage in a different form (as fats), and proteins are synthesized in ribosomes (with the help of mRNA, tRNA etc.) for various structural and functional roles in the cell, not primarily as an energy - creating molecule in chloroplasts.

Answer:

sugars
