Final answer:
Dendrites receive information, while axons send information.
Step-by-step explanation:
The key difference between dendrites and axons is that dendrites receive information, while axons send information.
Dendrites are branching extensions of a neuron that receive electrical signals from other neurons and transmit those signals to the cell body. In contrast, axons are long, tube-like structures that transmit electrical signals away from the cell body to other neurons.
