WebbThis North American pondweed is widely recommended for demonstrating oxygen formation during photosynthesis. Elodea is cheap and easy to grow, but other … WebbIn this experiment, the light intensity is changed, by decreasing the light intensity. The rate of photosynthesis should decrease and therefore the amount of oxygen bubbles should decrease. Hypothesis I think that if the light intensity is very low, then the number of bubbles of oxygen produced will also be very low,

Light intensity affects the rate of photosynthesis 3. The …
WebbFurther experiments into factors affecting the rate of photosynthesis a) Design a series of experiments, and explain what you would be looking for, to identify what the limiting factor for the rate of photosynthesis is, in this experiment, when light intensity is no longer limiting (don’t worry too much about how you would change or measure different factors … WebbTraditionally the production of oxygen and starch are used as evidence for photosynthesis. The light-dependent reactions produce a reducing agent. This normally reduces NADP, …
WebbThis is a reliable investigation to demonstrate photosynthesis, produced by Science and Plants for schools (SAPS). When the pond-weed Cabomba is placed in a solution of sodium hydrogen carbonate in the presence of light of appropriate intensity, it will begin to produce bubbles of oxygen-containing gas.
