whats a pseudopod
A pseudopod is a temporary extension of the cytoplasm found in certain types of cells, such as amoebas. It is used for locomotion and feeding. The word "pseudopod" means "false foot" in Greek, as the extension resembles a foot-like structure that the organism uses to move by flowing and extending in the desired direction.
