Pretty much any green plant part that uses photosynthesis.
The chloroplast is found in the plant and is key to photosynthesis. The chloroplast take in H20, CO2, and sunlight and give of Glucose (C6H12O6) and O2. It runs on two cycles known as the Calvin/Dark...
it undertakes photosynthesis, trapping light and energy using chlorophyll and converting C02 and H20 in lungs
makes energy and oxygen!
Although I'm not sure it was in my answer choices and that looked like the perfect answer believe me I'm in high-school
