In plants, Xylems are responsible for transport of

In vascular plants, there are two specialized tissues for transport: xylem and phloem.

• Xylem: It is responsible for the transport of water and dissolved minerals from the roots to the rest of the plant. This process is driven by transpiration pull and root pressure, and the flow is generally unidirectional (upwards).
• Phloem: It transports food (organic solutes like sucrose) and amino acids from the leaves (the site of photosynthesis) to other parts of the plant. This process is known as translocation and is bidirectional.

Oxygen is primarily exchanged through stomata via diffusion rather than being transported by the xylem. Thus, the xylem's primary role is the conduction of water.
