State a Practical that can be Used to See how the Rate of Photosynthesis can be Affected.

-Using Pondweed, to see how much Oxygen it makes in a Given Time is Excellent for finding out how Factors affect the Rate. -Have the Pondweed submerged in Water, that's all in a Glass Thin Cylinder. Then have a Tube that will take the Oxygen made to a Gas Syringe. [Remember not ALL the Oxygen will be there - some will be for Respiration] -Then, do the Experiment Normally with no Factors taking Place - to get a Base, Normal Result. -Then change one of the Factors and Repeat the Experiment with the SAME TIME.
