The tiny pores present on the surface of the leaves are called as 'X'. Large amounts of water can also be lost through the 'Y', hence the plant closes these pores when it does not need carbon dioxide for the process 'N'. The opening and closing of the pore is a function of the 'Z'. When water fIows into them, 'Z' gets swelled.
