Xylem in the plants are responsible for the transport of:

Result
Your answer: —  Â·  Correct: B
Explanation

In plants, the xylem is a specialized vascular tissue primarily responsible for the upward transport of water and dissolved minerals from the roots to the leaves and other parts of the plant [2]. This movement is largely a physical process driven by transpiration, where water evaporation from leaves creates a negative pressure that draws the water-mineral solution upward [3]. While the xylem handles water and inorganic solutes, the phloem is responsible for the translocation of organic food, such as sugars produced during photosynthesis [2]. Minerals obtained from the soil are dissolved in water and move through the xylem vessels, which are typically composed of dead, lignified cells that provide structural support [3]. Therefore, the xylem's function encompasses the transport of both water and the essential minerals dissolved within it [1].
