1. AmoebaBy: Reece Hill

2. Amoeba Amoeba is a genus that includes species such as Amoeba proteus. Amoebidae is a family that includes the Amoeba genus, among others. Amoebozoa is a phylum that includes the Amoebidae family, among others. Amoeboids are organisms that move by crawling.

3. The inside of an amoeba is a jelly-like fluid called cytoplasm. Bits of food and other materials float around in the protoplasm. Amoebas are so tiny that you need a microscope to see them. They live in water, including lakes, ponds, streams, rivers, and puddles. Some can even live in the bodies of animals.

4. Reproduce The psuedopod is used to help the amoeba move, and also to eat. It is a part of the amoeba's body that it can stretch out and pull itself with. Or, to eat, the amoeba stretches out the pseudopod, surrounds a piece of food, and pulls it into the rest of the amoeba's body. Amoebas reproduce by a process called binary fission. This means that one amoeba can split in half and make two new amoebas.

5. As amoebas get older they increase in size. When big enough they spilt in half to create two cells that are identical genetically to each other. The process starts by having the nucleus of the cell, where they divide into two identical nuclei. The body of the amoeba then draws apart until it separates. Each chunk has one of the new nuclei. The new amoeba eat and grow until they spilt again.

6. The word amoeba comes from a Greek word meaning "to change." The amoeba moves by continually changing its body shape, forming extensions called pseudopodsinto which its body then flows. The pseudopods also are used to surround and capture food—mainly bacteria, algae, and other protozoa—from the surrounding water. An opening in the membrane allows the food particles, along with drops of water, to enter the cell, where they are enclosed in bubblelike chambers called food vacuoles. There the food is digested by enzymes and absorbed into the cell. The food vacuoles then disappear. Liquid wastes are expelled through the membrane.

7. Water from the surrounding environment flows through the amoeba's ectoplasm by a process called osmosis. When too much water accumulates in the cell, the excess is enclosed in a structure called a contractile vacuole and squirted back out through the cell membrane. The membrane also allows oxygen to pass into the cell and carbon dioxide to pass out.
