HINT: Does it balance?
In photosynthesis, light energy trapped by chlorophyll splits water molecules, releasing the oxygen to the air. The hydrogen then combines with carbon dioxide to form glucose.
What are the inputs and outputs?
Like mitochondria they have many folded layers of membrane
Photosynthesis can be summarised by the following equation:
location of the chloroplasts in the mesophyll cells
Photosynthesis is a process controlled by

Other photosynthetic organisms (e.g. algae and trees) also perform this process.
