The part of the plant that absorbs water and nutrients is the root. Roots serve as the anchor for plants, stabilizing them in the soil while also playing a crucial role in nutrient uptake. Through tiny root hairs, plants efficiently absorb water and essential minerals from the soil, which are then transported to different parts of the plant via the vascular system. Roots also store energy in the form of carbohydrates, supporting the plant's growth and development, particularly during adverse conditions when above-ground growth slows.
