Answer
Stomata and lenticels
Reason — Stomata are tiny pores present on the surface of leaves and lenticels are present on stems.
Stomata help in gaseous exchange and transpiration. Veins transport water, minerals, and food.
Lenticels help in gaseous exchange and sepals protect the flower bud.
Hydathodes are responsible for guttation.
