Please someone explain briefly these terms as related to photography

Generally speaking:
Micro = Captured image on the "film/sensor" is LARGER than the actual subject size.
Macro= Captured image on the "film/sensor" is equal to the actual subject size.
Close-up refers to subjects that do not fit the categories listed above but are generally taken from a relatively short distance (usually less than 2-3 feet, or with a telephoto that makes it look like you are right close to the subject.

In 35mm film terms, Macro would mean the film frame (1" x 1.5" ) contains a subject that in real life is THAT EXACT size (at least the captured portion of it). In digital terminology, it depends on the camera used. Also what some lens mfg call "Macro" is really just "close-up".

There are others that may be able to explain it better, but this is a very "basic" breakdown.

Thanks, I wanted a basic explaination. That is what I thought the terms ment.

Just to add a spot of unclarity, Nikon refers to its macro lenses with the term "Micro."

Looks like you covered all the bases. Recently saw a brief definition for macro: Must be at least 1:1, anything less is close up.

Fine...One more thing to get me more confused than I already am...I think I'll stick with the term "close up". After all said and done, to me they are all close ups.

Most "normal" lenses will focus to around 1:4, so, loosely defined close up to be 1:4 up to 1:1 . Since most lenses will not focus closer than 1:4, and a "macro" lens will, most people ( and lens manufacturers ) conotate this to be the "macro" range instead of just close up.

I agree with this definition of "close-up" photography.
In comparison, a true macro lens will capture 1:1 at MFD, and can capture 2:1 or greater with extension tubes. Only one lens (Canon MPE-65) will capture 1:1 to 5:1, without tubes, and it is absolutely considered a macro lens. Further, microscopy start at 10x (like the microscope in every jewelry store), so photo-micrography is also defined at 10:1 magnification (10x life-size).
