1. Protist- animal like
By: Jamie, Joe and Aaron .

2. Principal characteristics
The prostists are classified by the type of locomotion. Also by criteria such as types of organelles , life cycle , mode of reproduction, nutrition and if the organism is free living or parasitic.
They are classified in four different groups
Zooflagellates - flagella
Sarcodines - extensions of cytoplasm (pseudopodia)
Ciliates - cilia
Sporozoans - do not move

3. Corporal Structure
Protists are eukaryotes and depending on the type of protists determines whether or not they have symmetry. For example , paramecium has binary symmetry but the plasmodium flaciparum ( malaria ) does not have any symmetry at all.

4. Reproduction
Protist use both sexual and asexual reproduction or both . With the asexual reproduction it is by binary fusion. Multiple asexual division occurs in some forms. Sexual protists ( gametes) is unclear how frequently sexual reproduction causes genetic exchange between different strains of plasmodium.

5. Circulation
Protist don’t have a circulatory system because they are a single celled organisms . They get there energy by diffusion through the cell wall.

6. Digestion
They are hetotrophs . They digest there food by phagocytosis .They generally move around to get food. They eat bacteria and other micro organisms . But Saprozic organisms absorb pre-digested or soluble nutrients directly through cell membrane. Although the algea

7. Nervous system
Protist do not have a nervous system because they are unicellular , but they do have a nucleus. And in some cases ( for example the paramecium ) they have two nuclei.

8. Respiration
Because the protist are unicellular they can take in raw materials and give out waste through diffusion.

9. Habitat
Prostist live in a diverse amount of habitats, mostly moist environments. Like fresh water or salt water. All protists are aquatic or live inside a host.

10. Sample organisms Plasmodium Falciparum (malaria);
Malaria is caused by four protist that make up genus plasmodium

13. Interesting facts
Protist first appeared on fossils 1.5 billion years ago
To small to be seen with the naked eye
They can only live in water or in a host.
They are all unicellular.
