The xylem primarily transports water and minerals obtained from the soil.

The two conducting tubes in plant transport systems are the xylem and the phloem.

Plants have low energy needs because they do not move, and a significant portion of their tissues consist of dead cells. As a result, they can utilize relatively slow transport systems.

Capillaries are the smallest vessels in the circulatory system with walls only one-cell thick. They facilitate the exchange of materials between the blood and surrounding cells, allowing for the delivery of oxygen and nutrients and the removal of waste products.
