Diodes are made from one PN junction. They have only two layers, and so have two terminals or leads.
Transistors are made from one PN junction and one more n- or p-type. They have three layers, and so have three terminals or leads.
Diodes operate like switches or one-way valves. Ideally, they allow current to flow in only one direction.
Transistors function can be modeled as valves or gates. The current flow through the middle layer controls the flow through the other two layers.
