Protists

Amoeba
Movement
The amoeba moves by their pseudopods changing shape.
Reproduction
They reproduce by the nucleus of the parent cell splitting in half by fission and then there are two daughter cells.
Eating
The amoeba eats by surrounding the food particles and the food goes to the pseudopods. This process is called phagocytosis.
Reactions
The amoeba reacts because water passes through the ectoplasm, but if too much water comes through, the contractile vacuole squirts out the membrane.
Amoeba Feeds!
Euglena
Movement
The flagellum twirls around throughout the water.
Reproduction
The euglena goes through a process called mitosis. They usually duplicate more in warm water and sunlight.
Eating
The eyespot detects light for the chloroplasts. The chloroplasts then make food for the euglena through a process called photosynthesis.
Reactions
The euglena has an eyespot.

Paramecium
Movement
The paramecium moves by it's cilia.
Reproduction
The parameciums reproduction system happens through a process called conjugation.
Eating
The cilia moves the paramecium through water, but also helps the paramecium eat. The cilia sweeps up food and water and then it goes through the oral groove.
Reaction
This organism eats bacteria off of decaying plants. Some live inside of the protoplasm.
Paramecium eats diatom
Volvox
Movement
Their flagella beat on each other, there are two flagella. When they beat, the ball like body rolls around through the water.
Reproduction
When the Volvo's daughtre mature, the parent ball bursts open and the tiny daughter colonies get released.
Eating
Their chlorophyll makes their own food through a process by the name of photosynthesis.
Reactions
These Volvo's are really really big, you don't even need a microscope to see them. They are visible to the naked eye. Although for a good view of their daughter colonies and how they eat, you would need a microscope.
