Pseudopods or pseudopodia (false feet) are temporary projections of eukaryotic cells. Cells having this faculty are generally referred to as amoeboids.
Formation:
First, the cell surface extends a membrane process, termed a lamellipodium. Polymerization of actin takes place and form filaments at the leading edge, which subsequently will blend into one another to form networks. It is supposed that actin polymerization is at the origin of the force propelling the cell forwards.
Mechanical role:
Pseudopods are one of the three locomotion modes of unicellular organisms (together with flagella and cilia). projection of cytoplasm
Sensory role:
Pseudopods also capture prey by phagocytosis. Phagocytosis pseudopods have arisen in a number of different protist groups, but also in some cells (phagocytes) in multicellular organisms.

protist?!
Do you mean "protozea"?
A pseudopod is the mass of the cellular body that reaches out and engulfs whatever nutrient is available.

The prefix pseudo- means "fake" or "false". So a pseudopod would have "false" feet, or "false" legs.

One of its blobby "limbs" that it uses to crawl around.
