Is this an AP lab?
The DPIP replaces NADP+.
In photosynthesis, NADP is reduced to NADPH, but NADP is colorless.
DPIP replaces the NADP. When DPIP is reduced, it changes from blue to clear. DPIP is used to show photosynthesis taking place.
If you are referring to the "Plant Pigments and Photosynthesis" Lab Then, the DPIP is used to substitute NADP+. In photosynthesis, electrons are normally transferred to NADP+. However, DPIP will take its place in this experiment. DPIP is normally blue. When it is reduced, or gains electrons, it will turn colorless. DPIP is used to show that photosynthesis is taking place.
Darkness slows down the reduction of DPIP because the reaction requires light energy to drive the reduction process. In the absence of light, the electrons from the reducing agent (e.g., sodium ascorbate) are not activated, and therefore the reduction of DPIP does not occur at the same rate.
Adding more DPIP to each tube would likely result in a faster color change, as more DPIP molecules would be available to accept electrons from the reduced chloroplasts. This would lead to a quicker reduction of DPIP and a faster transition from blue to colorless, indicating a higher rate of photosynthesis.
DAB, or diaminobenzidine, is often used as a substitute for DPIP in living plants to detect the presence of hydrogen peroxide, a reactive oxygen species. It forms a brown precipitate upon oxidation and can be visualized under a microscope to indicate the presence of hydrogen peroxide in plant tissues.
Boiling chloroplasts prevents the DPIP from being reduced because the enzymes for photosynthesis are no longer present in the chloroplasts. DPIP is reduced from blue to colorless when light strikes the chloroplasts and the electrons are boosted to a higher energy level. Since photosynthesis cannot be performed by the denatured chloroplasts, the DPIP cannot be reduced.

Adding more DPIP to each experimental tube would likely result in a faster rate of color change or a more pronounced color change in the experiment. DPIP is a redox indicator that changes color as it accepts electrons during the photosynthetic process. Increasing the amount of DPIP can make the color change more noticeable due to a higher concentration of the indicator molecule being reduced.
The source of electrons that will reduce DPIP is usually a plant extract or isolated chloroplasts. In the process of photosynthesis, electrons are transferred from water to DPIP through the photosynthetic electron transport chain, leading to the reduction of DPIP.
Because it was the control. Note how all other cuvettes had DPIP. We did not really know what dpip's effect on the % light transmittance was, by adding a ontrol, we could not compare and contrast.

DPIP (2,6-dichlorophenolindophenol) is used as an artificial electron acceptor in laboratory experiments to measure the rate of photosynthesis. It acts as an electron carrier, accepting electrons from photosystem I in the light reactions of photosynthesis. By monitoring the reduction of DPIP from blue to colorless, researchers can quantify the rate of electron transfer and ultimately the rate of photosynthesis.
Electron capture by a dye like DPIP (2,6-Dichlorophenolindophenol) usually leads to a color change in the dye molecule. In this process, the dye molecule accepts an electron from a reducing agent, causing the dye to change from blue (oxidized form) to colorless (reduced form).
