Question

How will you prove that plants take in carbon dioxide during photosynthesis?

Answer 1

Answer:

Plants extract the carbon dioxide from the air and use it in photosynthesis process to feed themselves. The carbon dioxide enters the leaves of the plant through small pores called stomata. Once the carbon dioxide enters the plant, the process begins with the help of sunlight and water.

Proof that CO 2 is observed and used up by Plants :

Yes, it will work satisfactorily. Lime water absorbs carbon dioxide and hence there is no carbon dioxide for the leaf and hence photosynthesis does not take place and no starch is prepared. Hence on iodine test, the presence of starch is negative and thus proves that carbon dioxide is required for photosynthesis.
