Protists Description

Protist Characteristics

eukaryotic one-or many-celled organism that lives in moist/wet environments; some are plant-like and contain chlorophyll;some are animal-like and can move Protist
Protist are difficult to classify; they are grouped based on characteristics shared with plants, animals,and fungi
the evolution of protist is studied through fossils and genetic material
Plant-like protist that contain chlorophyll to make food Algae
Found in fresh and salt water, make glasslike boxes which can form fossils Diatoms
Also known as fire algae because they produce a chemical that causes them to glow in the dark;use flagellum to move in their salt-water enviroments Dinoflagellates
long, thin, whip-like structure used for movement flagellum
Have characteristics of both plants and animals; when light is present they make their own food; an eyespot helps them move toward light;when there is no light, they eat bacteria and other protist. Eugenoids
also called sea weed;are usually many-celled; can live at the depth of 175 m; contain chlorophyll and large amounts of red pigment. red algae
contain large amounts of chlorophyll and can be one-celled or many-celled; some scientist say they evolved from green algae. brown algae
a many-celled form of brown algae; is an important source of food and shelter for aquatic(sea-life) organisms kelp
Algae,a source of food for ocean organisms are called grasses of the ocean
Algae produce oxygen through photosynthesis
Results of imbalances that can cause enviromental problems is called an algae bloom
Algae can be used for food and cosmetics
One-celled animal protist protozoans
Thread-like structures that extend from their cell membranes cilia
have two nuclei;the micronucleus is involved in reproduction while the macronucleus controls other cell functions paramecium
Ciliates eat bacteria
Means "false foot"; are used by some protist to move about and trap food. pseudopods
One-celled protist reproduce asexually
3 types of protist groups plant-like , animal-like, funguslike
Animal-like protist protozoans
plant-like protist algae
funguslike protist slime mold, water molds, and downy mildews
These are parasites that cause disease Amoebas
