What's the difference between iso-surface and plane

Hello everyone!
I'm learning ANSYS Fluent now, and I'm puzzled with the difference between Iso-surface and plane in creating surface in fluent cases. Can you tell me the difference? Thanks

Iso-surface is a surface where some variable is the same.
If you make that variable for the iso-surface x=0, that would be the YZ plane.
but if you made it temperature=100K, it would be all locations that were exactly that temperature, which could be any irregular shaped surface, not just a plane.
