Expert Answer:

Xylem.                                                                                                                

Xylem is involved in the transport of water and minerals from roots to aerial parts of the plant. Blocking of xylem decreases or stops the water transport in plants, thereby causing the wilting of the plant.

 

(In addition, blocking the stomata of the leaves will also cause their wilting. This is because stomata are the pores through which gaseous exchange occurs during photosynthesis and respiration.  In addition, transpiration also occurs through stomata. Transpiration pulls more water up through the xylem. So if stomata are blocked, both photosynthesis and transpiration would be affected. This will be harmful for the plant. Such a plant will soon wilt and die.)
