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.
