amoeboid movement

hey! i have got a classproject on ameoboid movement. well they specified the sol and gel therory. so does anyone know some good websites where i could get the information from ?? pls help
the points that i have to give are somewhwat like this :

* what is sol and gel theory ?
*who discovered it ?
*importance of the theory ? etc..

please help, thanks !!

Here is a basic definition. It also covers sol-gel theory.

This article has a bit more information on the different types of amoeboid locomotion and the processes involved.

And this article goes into even more depth, proposing that there is another process in addition to sol-gel theory that contributes to amoeboid movement.

All these were found with a quick search for "amoeboid movement". Google is your friend.
