Unit 5 – Lesson 3

Protists

• Protists are single cell organisms• Can be producers and consumers• They are known as they “odds n ends” of life.

– Mushroom like– Plant like – Animal like

Fungilike Protists

• Slime mold– Consume once living plants– Decomposers

Plantlike Protists• Algae

– Algae provides food for many animals and animal-like protists. They are a staple of aquatic ecosystems.

• Largest producers of OXYGEN thru PHOTOSYNTHESIS

Plantlike Protists– Algae can also help remove pollution – the use pollution

as a food source and can over produce.

All About Algae

• Is algae good or bad?

• What are we using algae for in today’s society?

Oligotrophic Lake Eutrophic Lake

Animallike Protists

• Paramecium – has cilia – short hair-like projections

Animallike Protists

• Amoeba – moves with a pseudopod (foot like projection)

Protozoans• Protozoans are important members of ecosystems.

– Decompose matter in the environment– Can cause disease

• malaria

Fungi• Fungi are multicellular consumers• They consume their food through absorption of

dead organisms

Fungi

• There are four types of fungi:– sac fungi– zygote fungi– club fungi– imperfect fungi

Club Fungi

• Example: Mushrooms

Zygote Fungi

• Example: Mold on bread – grow in moist areas

Sac Fungi

• Example: Yeast Fungi, Diaper Infection Fungi

Imperfect Fungi

• Examples: fungi in Blue Cheese, Athletes foot
