It’s a single cell’s equivalent of a foot. The cell sticks it forward, digs it into the ground, and pushes itself forward with it.
Interestingly some cells have things like the studs on football boots (“eupodia”) to help get a grip…

So, how would a cell with a peudopod react to zero gravity?
Robert commented on :
I don’t think it would change anything. Cells are so tiny, they’re much more worried by things like surface tension and adhesion than by gravity (indeed, it was recently shown that cells can walk on the surface of a liquid with pseudopods)
