Euglena, Amoeba, Volvox, and Paramecium


The euglena does many things. It moves by it's flagella and it whips around and only has one. It reproduces by splitting itself called the process of mitosis. They make their own food using photosynthesis, they can also absorb food through their cell membrane in their environment.

The amoeba is a very interesting protist, with it's cytoplasm body it moves by changing it's shape then creating pseudopods. It reproduces asexually through a process called binary fission which is splitting itself. They eat by surrounding it's pseudopods around tiny food particles. They respond to their environment when a pond or puddle dries up and then creates a hard shell around itself called cyst and survive when it gets dry.

The volvox is a circular shaped protists unlike most. It moves by having two flagellum that beat together and roll the ball through the water. The volvox reproduces by having daughter colonies. When they mature parent colonies burst open and release the daughter colonies. They eat by having chloroplast and using photosynthesis to make their own food. They live together in a colony composed of 500-50,000 cells.

The paramecium are more shaped like the bottom of a shoe! They move by using it's cilia in the water. They can reproduce asexually (binary fission) or sexual reproduction called conjugation. They eat by using it's cilia to sweep food and water into the oral groove. It can also shoot out tricocyst.
