Question

Q14 On application of Vaseline on the surface of leaf, will the gaseous exchange
take place in plants? Justify your answer.​

Answer 1

Answer:

Vaseline is applied on the surface of leaves of a potted plant. ... This prevents loss of water vapour and the moisture of the leaf retain for sometimes. But as the layer of vaselin stops all type of gaseous exchange, both photosynthesis and respiration also cannot occur. As a result the leaf will gradually die.
