Solution

The correct options are
B
Inhibits CO₂ intake by plant.

C
Stops the glucose/ starch production in leaves.

KOH or Potassium hydroxide is an absorbent of carbon dioxide. In the closed jar, entire carbon dioxide is absorbed by KOH. This does not allow production of glucose or starch as glucose is produced by the reduction of carbon dioxide during the process of photosynthesis.

In this experiment, how does KOH affect the process of photosynthesis in the plant kept in bell jar ?

The production of starch, and not glucose, is often used as a measure of photosynthesis in leaves because

(a) starch is the immediate product of photosynthesis.

(b) glucose formed in photosynthesis soon gets converted into starch.

(d) sugar cannot be tested.
