Kingdom Protista Mr. Chapman Chemistry 30

Different Types of Protista

The First one is a Bacterium...

Recall The Details of the Kingdom... Very Diverse All Eukaryotic Autotrophic and Heterotrophic Most reproduce asexually, a few can reproduce sexually.

Details Continued... Most are free living, but a few are parasites. Microscopic Classified based on how they move, but very difficult to classify.

The General Definition of a Protist: A protist is a eukaryote that is not a plant, animal or fungus.

3 Types of Protists: Animal-like Protists Plant-like Protists Fungus-like Protists

Animal-Like Protists The defining feature of animal-like protists is that they are all heterotrophs. This means that animal-like protists consume other organisms (see page 573 of text). All animal-like protists, however, are unicellular. In other words, they are composed of a single cell. This is different from animals, as all animals – no matter how simple – are composed of many cells.

Plant-Like Protists Plant-like protists are like plants because they are able to make their own food using chloroplasts. Plant-like protists do not, however, have roots, stems or leaves and this is what makes them different from plants. Plant-like protists are interesting in that they can be unicellular, colonial, or multicellular.

Fungus-Like Protists Fungus-like protists decompose dead organisms, and examples of them include things such as slime molds. Fungus-like protists used to be classified as a part of kingdom fungi, but this changed because during a part of their life cycle, fungus-like protists can move. More to follow on actually fungus later in the unit.
