Biology
Look at the experiment shown in figure below. Suppose you took a single flower with a long stalk dipping in water, instead of a leafy twig. Will it serve the purpose? Yes/No. Give reason.
Answer
No, it will not serve the purpose because the number of stomata is much lesser on petals as compared to leaves. Moreover, there are no roots also to actively absorb water and increase the rate of transpiration. Hence, the water loss through transpiration will be negligible in this case.
