The process demonstrates the loss of water that has appeared in the polythene bag is transpiration. As the potted plant is kept in the sun. ... As we keep the pot in the sunlight the stomata will open and the loss of water i.e., transpiration takes place from the aerial parts of the potted plant and the stomata.
