Flashcards

Amoeboid Movement

A type of cell movement resembling the movement of amoeba, where the cell changes its shape by extending temporary projections called pseudopodia.

Pseudopodia

Temporary, finger-like projections of cytoplasm that extend from the cell membrane, aiding in movement.

Leucocytes

A type of cell found in the blood responsible for fighting infections and foreign bodies in the body.

Phagocytes

Also known as macrophages, these large cells engulf and destroy harmful substances or cellular debris in the body.

Microfilaments

These are essential components of the cytoskeleton, involved in cellular movement, shape, and internal organization. They are made up of proteins like actins.

Study Notes

Amoeboid Movement in Specialized Cells

Specialized cells like macrophages and leucocytes in blood use amoeboid movement.
This movement is similar to how Amoeba moves.
Pseudopodia, extensions of the cell, are formed by the flow of protoplasm.
Cytoskeletal elements, specifically microfilaments, play a role in this movement.
