Explain the process of production of food in plants.

उत्तर
Leaves are the food factories of plants. They are the sites where the synthesis of food occurs in plants. The leaves of plants contain a green pigment called chlorophyll. This pigment captures the sun’s energy, which is used to prepare food from carbon dioxide and water. The process of synthesis of food using sunlight, carbon dioxide, and water is known as photosynthesis. During the process of photosynthesis, the leaves containing chlorophyll convert carbon dioxide and water into carbohydrates in the presence of sunlight. Carbohydrates, which are produced during photosynthesis, are ultimately converted into starch to be stored in plants. This process can be represented in the form of the following equation:
\[\ce{6CO2 + 6H2O ->[Chlorophyll][sunlight] \underset{(Glucose)}{C6H12O6} + 6O2}\]

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
