If you had a dye that turned bright red when the pH increased, AND, if you had a way to block the Calvin cycle, then shining light on the living chloroplast would turn the stroma bright red. When water is split during the light reaction, the electrons first travel to P680 before they go anywhere else. The end product of the Calvin cycle is glyceraldehyde 3 phosphate. Isolate chlorophyll from its electron acceptors and it will fluoresce green after photoexcitation by energetic light. The only light that can be used for photosynthesis is between 600 and 750 nm.
Carbon dioxide enters the leaf through pores called stroma.
2F, it is found in the stroma. 3F, only ATP is produced. 4T 5T 6F, it represents inorganic phosphorus. 7T 8F, they transmit or reflect green.
