    How was Biology Paper 42

    owh crap. yea i gave thick cuticle , sunken stomata. But i also said that they have air sacs to supple oxygen , ethanol dehydrogenase to increase tolerance to ethanol produced. And i tried to elaborate on them abit but wasnt sure if it's enough for 8 marks soo i included the cuticle ,stomata points.
