Pseudopod - English Definition & Meaning

Definition

A pseudopod is a temporary extension of the cytoplasm in amoeboid cells, used for locomotion and feeding. Think of it as a cellular "false foot" that helps the cell move or engulf food. It's formed by the dynamic rearrangement of the cell's cytoskeleton. These structures are essential for amoebas and other similar cells to navigate their environment. Imagine it like a flexible arm that reaches out and pulls the cell along. This ability is fundamental to how these single-celled organisms live and interact.

Etymology

The word "pseudopod" comes from the Greek words "pseudo" (false) and "pod" (foot). The name directly reflects its function as a temporary, foot-like extension. The term was coined as scientists observed and described the movement of amoebas. The etymology clearly conveys its appearance and role.
