The part of a plant that absorbs nutrients and water is called the root. Roots anchor the plant in the soil and are essential for its stability. They absorb water and essential minerals from the soil, which are vital for the plant's growth and development. Roots also play a significant role in storing energy reserves, which can be utilized during periods of dormancy or stress. There are various types of roots, including taproots and fibrous roots, and they adapt to various soil conditions to optimize nutrient uptake. Healthy roots contribute directly to the overall vitality of the plant.
