Question

describe the half leaf experimeny to show co2is necessary for photosynthesis​

Answer 1

Explanation:

In Moll's half leaf experiment a destarched plant is used.Half part of one of the leaves from the plant is inserted into a corked bottle containing either KOH solution or KOH palletes. The plant is then placed in sunlight for a few hours. The leaf is then tested for starch with iodine solution. Part of the leaf that was inserted in the bottle does not turn blue or test positive for starch. This is because CO2 present in the bottle was aborbed by KOH and the bottle was corked to prevent any entry of air.Proving that CO2 is essential for photosynthesis.
