They are simply different interface types for graphics cards. Compatibility between any given video card and a motherboard is determined by the type of graphics interface they have.
No, you cannot put an AGP graphics card into a PCI-Express slot.
A PCI-Express interface only works with a PCI-Express graphics card. An AGP interface only works with an AGP graphics card.
The main difference is speed. PCI-Express is newer, and the highest PCI-Express speed is x16. The highest AGP speed is x8. Allegedly, PCI-Express is faster than AGP. However, it has been argued that there is not much difference in performance between these two slots.

The speed difference is mainly due to the fact that the graphics card don't utilize the extra bandwidth available. But even then, there's still some minor differences.
Also, bear in mind that they are phasing out AGP. Newer cards are now produced for PCI-E. This includes low end cards, so in the near future, all motherboards should come with just PCI-E slots. Just like how they removed the ISA slot and replaced it with PCI.
