Analogy type questions:
$(1)$ Stomata : Transpiration :: Hydathode : ..........
$(2)$ Phloem : Translocation of sugars :: Xylem : ..........

(A) $(1)$ Guttation
$(2)$ Water and minerals
Explanation:
$(1)$ Stomata are the sites for transpiration (loss of water vapor). Similarly,hydathodes are the specialized pores through which guttation (loss of water in liquid form) occurs.
$(2)$ Phloem is responsible for the translocation of sugars (food) from source to sink. Xylem is responsible for the transport of water and dissolved minerals from roots to other parts of the plant.
