Think about kernels as a car's engine. The device is the car, the ROM is the interior, and the kernel is the engine. Kernels do under the hood modifications, often things like improving battery life, or built in overclocking.
That being said, you are generally not required to flash a custom kernel to a ROM, if you are, the instructions will tell you to.
