All members are eukaryotic, which means that they all have _______________ like a nucleus and mitochondria.

Some are ______________ (single celled) while others are ___________________.

Most protists are

The cell wall is composed of ________________, which humans cannot digest. Humans lack the _________ needed to digest cellulose.

Most Protists are asexual and reproduce by binary fission/mitosis. Others reproduce sexually through conjugation.

They are divided into 3 groups based on similarities.

Some of the protists are plant-like (algae), while others are animal-like (protozoans) and still others are fungus-like (slime molds).

Phylum Sporozoan Plasmodium

Dinoflagellates

Phylum Sarcodina Entamoeba histolytica

Trypanosoma cruzi Blood sucking insects known as kissing bugs act as the vectors of Chagas to humans.

Phylum Zoomastigophora Trichomonas

KINGDOMProtista PHYLUMProtozoa CLASSCiliata ORDERHymenostomatida FAMILYParameciidae GENUSParamecium SPECIESParamecium (many species) Paramecium are helpful by controlling algae, bacteria, and other protists. They also help clean up tiny particles of debris in the water, and they feed small animals.

Macrocystis or giant kelp contains an emulsifier that is added to ice cream, salad dressing, toothpaste, cosmetics and hundreds of other products.

These are the fungus-like protists. They form delicate structures when on their food supply. They are considered decomposers because they obtain energy from breaking down dead organisms.

Some use spores that are released in order to reproduce.

Phylum Myxomychophyta Slime molds

Phylum Oomycophyta Water molds

“first”“animals”

These are the animal-like protists. They are also known as ZOOplankton. They are all unicellular heterotrophs. They are grouped according to their method of movement.

Phylum Sarcodina Amoeba Proteus

Phylum Ciliophora Paramecium

Phylum Ciliophora

Phylum Zoomastigophora Trichomonas

Phylum Sporozoan Plasmodium

Algae are the plant-like protists. Some algae are unicellular, while others are multicellular. All organisms are autotrophs,since they are photosynthetic.

Organisms in this group are considered __________________, because they are plant-like. They are eaten by the ZOOplankton. The groups are divided according to the color pigment they contain.

Phylum Pyrrophyta Dinoflagellates

Phylum Rhodophyta

Phylum Chrysophyta Diatoms

Phylum Chrysophyta Diatoms

Phylum Chlorophyta

Volvox

Phylum Chlorophyta Spirogyra

Phylum Phaeophyta Fucus

Phylum Phaeophyta Lamanaria

Moves by a flagellum. Photosynthetic…contains chloroplast so it is a photosynthetic autotroph. AN eyespot is used to move toward light. It is like a reflector.

Phylum Euglenophyta Euglena
