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 ...

A proper system of transportation is essential for plants, especially when distances between soil-contacting roots and chlorophyll-containing leaves are large. Without an efficient transport system, essential raw materials and energy may not be adequately distributed throughout the plant.

Roots are responsible for absorbing nutrients such as nitrogen, phosphorus, and minerals from the soil, providing essential building blocks for plant growth and development.
