Hint: Through photosynthesis the plants produce their own food. The water is transported through xylem and the food and minerals is transported along the plant body through phloem. The excess water in the plant body will be removed through leaves.

Complete Explanation:
This is the after effect of the transpiration process. Transpiration is defined as the process by which the evaporation of water takes place from the surface of the leaves and it is released into the atmosphere. Transpiration is helpful in removal of excess water in the leaves or plant. The small pores on the under surface of leaves from which the water content is released, are called stomata. The water content that is released through the stomata, into the atmosphere or in this case the inner atmosphere of a glass jar, gets condensed and deposited on the wall of the glass jar. That’s how water droplets are seen on the wall of glass jars. The removal of excess water occurs in plants through transpiration.

Additional Information:
The transpiration process actually helps the plant to adjust or maintain their osmotic pressure and internal temperature, so that the proper transportation of food, minerals and water can take place. The Stomata can also regulate the rate of transpiration.

Note:
The removal of excess water occurs in plants through transpiration. Water droplets are seen on the wall of glass jars due to the release of the water through stomata by transpiration of the potted plant. Transpiration is one of the main processes which help the plant to maintain the osmotic pressure and thus the transportation of water and minerals.
