The name of the process by which plants absorb nutrients is called nutrient uptake. This process primarily occurs through the roots, which absorb essential minerals and water from the soil. Root hairs increase the surface area for absorption, allowing plants to efficiently gather nutrients vital for growth and development. Nutrient uptake is crucial for photosynthesis, energy production, and overall plant health. It is influenced by factors such as soil composition, moisture levels, and the availability of specific nutrients, ensuring that plants thrive in their environments.
