The primary function of a plant's roots is to anchor the plant into the soil and absorb water and essential nutrients. Roots serve as the plant's foundation, allowing it to remain upright and stable, which is crucial for access to sunlight. Additionally, roots play a vital role in nutrient uptake, extracting minerals and sustenance from the soil to support growth and metabolic processes. Some plants also use their roots for storage of carbohydrates and other compounds, especially during periods of dormancy or nutrient scarcity.
