Movement: Every volvox cell has two flagella. The flagella beat together to roll the colony through the wall.
Feeding: Volvox cells have chlorophyll and make their own food by photosynthesis.
Reproduction: Daughter colonies are small, dark green balls. When the daughter colonies grow up, the parent ball will burst open and release the daughter colonies.
Volvox cells have eyespots that sense light. The eyespot helps the volvox live by showing it where the light is so it gets enough amount of sunlight.
All members of the Phylum Ciliophora move by tiny hair-like projections called cilia.
Unlike the ameba, it cannot change its shape. It has a thick outer membrane called the pellicle.
Reproduction in paramecium involves the exchanging of DNA within the micronucleus.
Paramecium are heterotrophs, meaning they must consume food for their energy. Food enters the paramecium through the mouth pore and goes to the gullet.
Euglena move by a flagellum which is a long whip-like structure that acts like a little motor. Euglena also have an eyespot at the anterior end that detects light. That is how the euglena makes it food, the eyespot shows where the sunlight is and the euglena moves to the sunlight to make its food.
The simplest thing, the amoeba is made of one cell.
They are commonly found in ponds or lakes. They are shape shifters that sometimes appear as a blob, sometimes appear to have legs or arms that can surround their food. It should be noted that amoeba are not animals; however, they are classified in the protist kingdom.
Amoeba's eat algae, bacteria, plant cells, and other unicellular organisms. It engulfs or surrounds its prey and usually forms a kind of dome that makes escape impossible. Then, and only then, does the amoeba touch its prey.
