If the chloroplasts in a plant's cells became damaged, **the plant would not make glucose and oxygen.** Chloroplasts are essential for photosynthesis, the process by which plants convert sunlight into energy, producing glucose and oxygen as byproducts.
Answered by

Plant root cells lack chloroplasts because **roots are underground and are not exposed to sunlight.** Chloroplasts are used for photosynthesis, which requires light, so they are not needed in root cells that do not receive sunlight.
