suggest a detailed photosynthesis biology experiment regarding the limiting factors please.?

Answer 1

Another limiting factor is carbon dioxide. You could take a plant and seal it in an airtight container with some barium hydroxide for a few days. The barium hydroxide turns all of the CO2 into bicarbonate and the plant is unable to use it. Next you would check the leaves for starch production, no starch means no photosynthesis. To check for starch, use the iodine test. First, boil the leaves for 10 minutes in H2O, then boil for 10 more minutes in ethanol. After that, put the leaves in a petri dish with a few drops of iodine, dark blue color change means starch is present. No color change means no starch is present, and there was no photosynthesis.

Answer 2

One limiting factor is the intensity of the light. So you could measure the rate of photosynthesis in different levels of light. Change the light levels by putting layers of something porous or translucent between the light source and the plant or alga you are using. You might choose cheesecloth, waxed paper, tissue paper, containers of water, or something else to cut back on the light. Or you might just move the light source farther away. In either case, it would be a good idea to use a light meter to measure the amount of light reaching the plant.
