For lots more animations on cell strucure and function and cell transport, visit North Harris College.
This is quite a long presentation covering membrane structure and function and passive transport, active transport and vesicle transport:
There are many links in the presentation – clicky clicky!
The internet is awash with decent animations and video clips for this topic – your best bet is to enter the search term “_____ transport swf” and see what comes up.
