Say what the reasons (feeding etc) are and things like that. Then I would draw a few diagrams and put little notes under them. One with the cell next to a dot. It would have psuedapetia (cellualar extensions that help it move) going towards the dot. The next would have the cell with a vacuole with a dot in it and I'd say the particle had been engulfed. Finally I'd draw the cell with a bit where the vacuole used to be and mention the digestion and enymes involved.

Personaly i think that could be a bit too indepth, seems more like an answer to an essay question

That would be becuase I thought it was an essay question (or at least part of an essay question). We had something like that on the end of one of the essays I did, that only got about 3 marks.

Phagocytosis is the process by which cells engulf and take in relatively large solids. The solid(s) are engulfed and after this the engulfed material is in a intracellular vesicle.

This occurs in ameoba as the main method for obtaining food.
