Solution

The correct option is B Stomata and lenticels
  • Gaseous exchange is necessary for plants. Carbon dioxide is necessary for photosynthesis, which is taken in the form of air. For this purpose, stomata are present on leaves, stems, and other organs. Stomata are the pores present on the epidermis.
  • After the secondary growth, lenticels are formed on plant stems. Lenticels are pore-like openings present on the tree trunks. They are also involved in gaseous exchange.
So, the correct answer is option A.
