Truthfully, these terms are often confused by consumers, and agents, as well.
An apartment describes a style - usually describing a multi-unit, multi-level building with individual "apartments".......very often people think of these as rental units, but they can also be bought............as compared to.............
A condo or coop, which are are simply 2 forms of ownership.
Like the other agents here mentioned, these real estate products are different from each other which is why Trulia have categories for them. An apartment is the general term of a building that has several units in them, however the ownership could be coop or condo.
The jist is a coop is ownership similar to buying stocks for a long term lease, the building and all it's units are owned by the 'corporation' or 'coop'. For a condo, this is real property which at the end of the day is a deed for your actual apartment unit and 'tenancy in common' for the common areas and the land the buiding is on.
There was an inquiry about this before, please refer to this thread for more information. You can also find my detailed explanation there:

In a co-op, the entire building is owned by a single corporation. Instead of a deed, buyers get shares (stock certificates) in the corporation, and a proprietary lease that allows buyers to occupy a specific unit and lays down the rules and rights much like a lease in a rental building. (In fact, technically speaking, buyers of co-op apartments are referred to as â€œtenantsâ€ or â€œshareholders,â€ not â€œowners.â€ )
CONDO: Buying a condo is very much like buying a single-family house. You get a deed to the apartment that gives you ownership of the interior of your unit and the surface of its walls, as well as an undivided interest in the buildingâ€™s common elements. This is the type of ownership almost everyone has in mind when they think about buying a home, and almost all newer buildings are condos.
