Answer:

I don't know

Step-by-step explanation:

Can't see the photos or answer options.

Photosynthesis: happens within chloroplasts, which are found in most plant cells. Inside this chloroplast, there are sacs called thylakoids. Chlorophyll, a light-absorbing molecule captures solar energy from light; most likely the sun. The captured energy is then converted into ATP and NADPH molecules, also known as chemical energy. The molecules then give off high-energy electrons, and the electrons then move through electron carrier proteins within the thylakoid membrane. The protein within the electrons pumps hydrogen ions into the thylakoid from the surrounding gel-like fluid inside the chloroplast called stroma The hydrogens that get pumped from the electrons then build up within the thylakoid space. The hydrogen ions move back to the stroma through a protein channel. The electron transport chain picks up high-energy electrons and hydrogen ions to form NADPH. The molecules then are able to carry high-energy electrons to the second stage of photosynthesis. As mentioned, chlorophyll molecules release high-energy electrons. The electrons then traveled through an electron transport chain and were then stored in NADPH molecules with hydrogen ions. For this to repeat the electrons and hydrogen ions must be replaced. A water-splitting enzyme removes electrons for the water molecules and then supplied them to the chlorophyll molecules. In doing so, the water molecules split apart into oxygen molecules and hydrogen ions. The ions and chlorophyll are now available for future cycles of light-dependent reactions. The oxygen is released into the air, ending the photosynthesis process.

A simple explanation: The plant cells convert solar energy(sunlight) into food with the help of H20(water) and C02 (carbon dioxide) in turn in this process the plant releases oxygen.

Hope this helps you choose your answer. :)
