Download Pseudopods

• These whiplike appendages extend from the
surface of many types of eukaryotic cells. If
there are many of them, they are called cilia;
• if only one, or a few, they are flagella. Flagella
also tend to be longer than cilia but are
otherwise similar in construction.
• Cilia and Flagella are hairlike organelles that
branch out from the surface of the cell, where
they help in the movement. These organelles
can be found in any eukaryotic cells. Cilia are
present when there are short and large
numbers of organelles on the cell. Flagella are
present when there are long and few numbers
of organelles on the cell.
• Pseudopods (which translates to "false feet") are temporary
cytoplasm-filled parts of the cell wall that are able to change their
form in order to move. They are used in some eukaryotic cells to
move around or to eat. Most cells that do this are called
amoeboids. The amoeba is a common example.
• The cell wall makes a network of fibers. The cytoplasm flows into
the network and fills it up, similar to a net filled with gelatin. This is
able to move, lengthen, or shorten. The pseudopod extends from
the amoeba. Then the main part of the amoeba flows into that
pseudopod and the amoeba has changed its place.
• Pseudopods are one of the three locomotion modes of unicellular
organisms (together with flagella and cilia). Pseudopods can also
capture prey by phagocytosis. Pseudopedia are used by some cells
to move around. They can detect food and place it inside the cell.
The human white blood cell uses this way to get around.
