Because convection currents is the heating rising cooling process and if the crust and part of the upper mantle wasn't divided into sections the heated material couldn't rise up.
That is the current theory of plate tectonics.
A lava lamp can be used as an analogy to help understand mantle convection. In a lava lamp, heated wax rises to the top, cools and then sinks, creating a circular motion. This movement is similar to how the mantle of the Earth convects, with hot material rising and cooler material sinking, driving plate tectonics. Plate tectonics is driven by the convection currents in the mantle, causing the plates to move and interact at the Earth's surface.
The theory of plate tectonics explains the movement of plates by convection cells in the Earth's mantle. These convection cells are caused by the heat from the Earth's core, which creates movement in the semi-fluid asthenosphere layer of the mantle, leading to the movement of the rigid lithospheric plates above it.
The plate tectonics are powered by the heat generated from the Earth's core. This heat causes the movement of molten rock in the mantle, creating convection currents that drive the movement of tectonic plates over the Earth's surface.
Volcanoes don't help plate tectonics; volcanoes are the result of plate tectonics.
That is the current theory of plate tectonics.
A version of convection currents, occurring in the mantle, is thought to be the force behind plate tectonics.
They are the same thing.

A convection current, in simple terms, is a cycle that keeps bringing the cool stuff down and the hot stuff up. This current could move the plates as they ride on top of the hot magma.

Convection currents in the mantle create plate tectonics.
Plate tectonics describes the motion of the Earth's lithosphere which brings about continental drift due to convection currents.
