Solution

The correct options are
B
Inhibits CO₂ intake by plant.

C
Stops the glucose/ starch production in leaves.

This experiment demonstrates the requirement of carbon dioxide for photosynthesis. Potassium hydroxide (KOH) absorbs all the available carbon dioxide in the bell jar. As the jar is closed completely, no carbon dioxide is allowed from outside. In this situation, photosynthesis and starch or glucose production are inhibited.

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.

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

Photosynthesis in an aquatic plant was measured by counting the number of $O_{2}$ bubbles coming out of the cut end of the plant. What will happen to $O_{2}$ production if you use a pipe blow air from your mouth into water in the beaker?

Q. Write the experiment of the bell jar and pudina plant, performed by Priestly to prove that air plays a key role in photosynthesis.
