Answer all the questions quickly

Answer all the questions quickly An apparatus as shown below Was up to investigate a physiological p.ocess plants. The setup was kept in sunlight for hours. Droplets of water were then seen inside the jar. Answer (2015) the questions that follow : Water dmpletS Ben jar Covered potted plant (a) Name the process being studied. (b) Explain the pnxess named above in (c) Why was the pot covered with a plastic sheet ? (d) Suggest a suitable control for this experiment. (e) Mention two ways in which this process is EEneficial to plants. (f) List three adaptations in plants to reduce the above mentioned Wocess.

Dear student,
a) The process studied is transpiration
b)Loss of water through the pores present in leaves called stomata in the form of vapours is called transpiration. The stomata are the small pores present in the leaves. Transpiration helps the plants to take nutrients from soil. It also keeps the plant cool in hot weather conditions.

Role of transpiration in plants is as follows:

• Creates transportational pull for transport of water in plants.
• Provides water for photosynthesis.
• ​Helps in the uptake of  minerals from soil to upper parts of plant.
• Cools the surface of the leaves (due to the evaporation of water).
• Keeps the cells turgid; hence, maintains their shape.

c) The given experiment is being performed to examine the phenomenon of transpiration from the aerial parts of the plant.
Here, the pot is covered with an plastic sheet so that transpiration experiment set up could not get influenced by soil water evaporation and we could get only the droplets of transpired water on the bell jar from the aerial parts of a plant.
