The video tutorial explains the structure and function of plant roots, focusing on their role in water and mineral absorption. It covers the different zones of roots, including the meristematic, elongation, and maturation zones, and highlights the importance of root hairs in increasing surface area for absorption. The tutorial also discusses specialized root types, such as aerial roots, and the process of active transport, which involves the movement of substances against a concentration gradient using energy in the form of ATP.
