Kingdom Protista

Kingdom Protista

I've been doing things on the six kingdoms for a while, but I never really went in depth when talking about protists. So now it's time to start.

There are three kinds of protists.

1. Plant-like protists

2. Animal-like protists

3. Fungi-like protists

 

Today we will be mostly talking about the animal-like protists, which are actually called protozoa, but first lets get through the basics of protists.

• All protists are eukaryotic, just like fungi, animals, and plants.
• Most are microscopic, like bacteria.
• They are their own kingdom.

Now for protozoa. There are three ways protozoa can move:
1. They can move using a flagellum.
2. They can move using pseudopods.
3. They can move using cilia.

Flagella are long, whip-like tails that whip and spin to move the protozoan. Most of the time, protozoa with flagella live in water.

Pseudopods, or "false feet", are used by protozoa such as amoebas.
These "false feet" are basically extensions of the protozoa that the use to pull themselves or pull food towards them. The protozoa change their shape into these "false feet".

Cilia are tiny hairs on the protozoan's body that help it move. These are mainly used in water.

Now for the four protozoan groups. :)
The first three you already know, right? If not, you'll understand why I said that when you look at what they are:

1. Flagellates
2. Amoebas
3. Ciliates

Now the fourth one you won't know (probably).

4. Sporozoans

Sporozoans are parasitic, or they do not help their host and in many cases harm them. Symbiotes are the opposites of these, they help their host.
