Woah dude!

There are many types of protists!


Amoeba eats two paramecia (Amoeba's lunch)

How does the Amoeba move?

The amoeba moves by move it flexible membrane around. The video shows the flexibility of the membrane.

How does it eat?

As shown in the video it raps its victims in the membrane and then digest them. They do not use photosynthesis to make their food.

How does it respond to its environment?

When conditions are bad, such as a dry climate or receding water, the Amoeba will create something called a cyst. This is a hard shell that protects the Amoeba from bad conditions.


Euglena - Flagellum movement in phase contrast

How does the Euglena move?

As seen in the video, the Euglena have a stick thing on the top of them. This is called a Flagellum. They use this to move.

How does it eat?

These have chloroplasts which are little organelles that make food. It does this by using photosynthesis.

How does it respond to its environment?

The euglena have an eyespot. This is an organelle that detects sunlight. Why would it need to do that? It detects sunlight so it can help it photosynthesis. If it is in a shaded area of it habitat it will move to a more sunny one.


Amazing Microscopic HD Video! Paramecium Feeding!!

How does the Paramecium move?

It has little hair on the side of it and it moves around by waving them around. Kinda like a swimmer moving his or her arms, except a lot of them!

How does it eat?

These organisms feed on other organisms to get their food.

How does it respond to its environment?

They have a defense mechanism called tricocyst. These shoot out from the cell and makes it appear bigger.


Volvox Dances

How does the Volvox move?

The volvox actually have two flagella. They use it to move (and dance apparently) around.

How does it eat?

The volvox have chloroplasts for photosynthesis.

How does it respond to its environment?

They are all together in colonies, about 5,00 to 20,00 cells each.
