What are the differences? Nikon lenses?

What are the main differences between Nikon micro and macro lenses?

And what lens would you recommend for me to buy if I like to photograph portraits?

Nikon's name for their macro lenses are Micro-Nikkor lenses.

Here is a link to all the Nikkor lenses.

If you buy the Nikkor AF-S 60 mm f/2.8 macro lens, you can use it as a portrait lens as well.
