The correct answer is Experimental leaf 2 . Key Points - Loss of water to the air through evaporation from the leaves is called transpiration. - Leaves have numerous pores known as stomata on the bottom of their surface. - Stomata help the plants to take up carbon dioxide, which they use in photosynthesis or the process of food-making. - Plants need stomata to release the oxygen formed during photosynthesis too. - Hence, if the stomata are blocked, transpiration would not occur, and the leaves will remain fresh for a longer period. - On Experimental leaf 2 , Vaseline was applied underneath the leaf, thus stomata get completely blocked thereby preventing transpiration. Hence it'll dry up last.
