A ACL is a Active Control List - So you specify a rule in a list of rules that data on a certain ip and or port can access another port and or ip address.  In essence its more like a rule in a router, allow everything to flow unless you specifically want it to do something else.

Where as a firewall acts as a inbetween between a trusted network and a untrusted one, so you could make a firewall not allow any traffic into your network except that on port 80 or even except traffic from a certain IP address.
