2. The inside part of the thylakoid membrane is known as the lumen.
3. The outside part of the thylakoid membrane is known as the stroma.
4. In the outside part of the stroma, light-independent reactions take place.
5. Water (H₂O) is oxidized, and oxygen(O₂) is released.
6. The dark reaction occurs outside of the thylakoid.
