Answer:
B. Chloroplast
Explanation:
Plants are autotrophs, which means they make their own food. They do this through a process known as photosynthesis.
Photosynthesis turns carbon dioxide, water and light energy into glucose/sugar (the food for the plants) and oxygen.
This process is done in the chloroplast, a green organelle in plant cells. If the plants didn't have chloroplasts, they wouldn't be able to perform photosynthesis. So, they wouldn't have food, and they would die. Therefore, choice B-chloroplasts is correct.
