Final answer:
Chloroplasts are responsible for photosynthesis in plant cells, converting sunlight into energy. Without chloroplasts, plants would have to find alternative energy sources.
Step-by-step explanation:
Chloroplasts are organelles found in plant cells that are responsible for photosynthesis, the process by which plants convert sunlight into chemical energy. They contain a pigment called chlorophyll that absorbs light energy and uses it to produce glucose, a high-energy molecule. Without chloroplasts, a plant would not be able to produce its own energy through photosynthesis and would have to rely on other energy sources, such as obtaining nutrients from the soil.
