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 LakeEutrophic 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
