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.

Examples of nutrients absorbed by plants from the soil include nitrogen, phosphorus, potassium, calcium, magnesium, and various trace minerals essential for plant growth and development.

Changes in plant body design that increase distances between roots and leaves can make diffusion processes insufficient to provide raw materials to leaves and energy to roots. In such cases, a proper transportation system becomes necessary to ensure adequate distribution ...
