Ameba Moving With Its False Feet (Pseudopodia)

The ameba is one of the simplest of the protozoa. It can be found in ponds and rivers and on the surface of the leaves of water plants. It looks like a grayish blob under a microscope. Its shape is constantly changing as it moves along.

One characteristic of the ameba is its false feet, that scientists call pseudopodia. The false feet extend out and then the rest of the body follows the false feet along. The ameba eats little animals and plants. It sends out its false feet to surround the plant or animal and then pops it right into the cell!

The ameba has tiny sacs in its body called vacuoles. Some of the vacuoles have food in them. Others collect water and squeeze the extra water out.

Oxygen enters the ameba through its thin covering called a cell membrane. The carbon dioxide leaves the ameba through the cell membrane as well.

The ameba avoids light but swims faster in warmer temperatures. The ameba reproduces by splitting in half. This is called fission. The ameba's nucleus or center splits in half and goes to opposite ends of the cell. Then the cell narrows and splits in half.
