The Figure shown below represents an activity to prove the requirements for photosynthesis. During this activity, two healthy potted plants were kept in the dark for 72 hours. After 72 hours, KOH is kept in the watch glass in setup X and not in setup Y. Both these setups are air tight and have been kept in light for 6 hours. Then, Iodine Test is performed with one leaf from each of the two plants X and Y.
Which of the following steps can be followed for making the apparatus air tight?
- placing the plants on glass plate
- using a suction pump.
- applying aseline to seal the bottom of jar.
- creating vacuum
