In one of the experiments to demonstrate transpiration, we used cobalt chloride paper. What are the characteristics of this paper that suit the experiment?

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.

From the following list, pick out the parts through which the water vapour of transpiration leaves the leaf and rearrange them in proper sequence.

Xylem vessels, mesophyll cells, stoma, intercellular space and substomatal space.

Does diffusion play a role in the passage of water vapour from the leaf during transpiration? If so, how?
