The definition of a pseudopodia is a temporary protrusion of the surface of an amoeboid cell for purposes of eating or moving.
When the surface of an amoeba protrudes outward in order to reach food and then returns to normal, the protrusion is a pseudopodia.
- In Hydra the odcyte is a large amoeboid cell, which sends out pseudopodia amongst the odgonia and absorbs nutriment from them.
- Note that these phagocytic cells are pushing out protoplasmic processes (pseudopodia) by which they grasp their victims. (X woo diam.) FIG.
