Why the wings of the aircraft are divided into two parts?

The wings of an aircraft are often divided into two parts to enhance aerodynamic efficiency and structural integrity. This design allows for improved lift distribution and reduces the risk of wingtip stall, enhancing overall flight stability. Additionally, separating the wings into sections can facilitate maintenance and repair, and may accommodate different wing configurations for various flight conditions. This modular approach also allows for the incorporation of advanced technologies, such as winglets, which further improve fuel efficiency.
