What is the difference between a root hair and a lateral root?

Root hairs are small, hair-like extensions of root epidermal cells that increase the surface area for water and nutrient absorption from the soil. In contrast, lateral roots are branches that grow from the main root, helping to anchor the plant more securely and increase its access to nutrients and water. While root hairs are primarily involved in absorption, lateral roots contribute to the overall growth and stability of the plant's root system.
