How do roots function in hydroponics?

Roots in hydroponics play a crucial role in the absorption of nutrients, but they perform this function differently compared to traditional soil-based growth. In hydroponic systems, plants are grown in nutrient-rich water solutions where minerals and nutrients are dissolved. Consequently, roots are responsible for taking in these dissolved nutrients, which are essential for the plant's growth, development, and overall health.

Unlike in soil cultivation where roots rely on the soil to supply nutrients, hydroponic roots are directly immersed in a nutrient solution. This allows for more efficient nutrient uptake because the nutrients are readily available in a form that the roots can absorb effectively. Moreover, the absence of soil in hydroponics means that roots also do not serve the sole purpose of anchoring the plant; thus, while anchoring is still a function of roots, it is not the primary role they play in this system.
