Answer:
A. Chloroplast.
Step-by-step explanation:
Chloroplast is the cell organelle in plants and eukaryotic cells which is responsible for photosythesis. The plat needs energy to grow, this energy is produced out of food formed from the chloroplast's process of coverting sunlight into food, in the presence of water and carbon (IV) oxide.
This are similar to the mitochondria present in the cell of animals and is responsible for respiration, a process which produces energy as one of its main products.
