Protists and Fungi Notes pg 93

There are 2 kinds of protists: Animal-like: protozoa Plant-like: protophyta There are 2 kinds of protists: Animal-like: protozoa Plant-like: protophyta

In your notes, write down 2-3 examples of protozoa and 2-3 examples of protophyta

Protozoa - Diatoms

Protozoa - Dinoflagellates

Protozoa - Ameoba

Protozoa - Rotifer

Protophyta – Plant-like protists SOME plant-like protists are Multi-celled Such as algae SOME plant-like protists are Multi-celled Such as algae

Protophyta – brown algae

Protophyta – Red algae

Protophyta – Green algae

You use algae every day!

Fungi – pg 93 continued There are many different types of fungi Most of them are decomposers = they break down & feed off of dead and decaying material. There are many different types of fungi Most of them are decomposers = they break down & feed off of dead and decaying material.

ALGAE Kingdom: Protista

What do you know about Protists?

Diatoms Phylum: Bacillariophyta The largest group of protists Make a wall of silica Found mostly in cold marine habitats Look like little boxes with lids Photosynthetic The largest group of protists Make a wall of silica Found mostly in cold marine habitats Look like little boxes with lids Photosynthetic

Diatomaceous earth Used in sugar refining Swimming pool filters Silver and other metal polishes, toothpaste, and paint that reflects light Insulation around blast furnaces and boilers Construction panels in prefabricated housing Used in sugar refining Swimming pool filters Silver and other metal polishes, toothpaste, and paint that reflects light Insulation around blast furnaces and boilers Construction panels in prefabricated housing

Dinoflagellates Division: Dinophyta Two distinct flagella Photosynthetic Cause of harmful algal blooms The sudden multiplication of dinoflagellates Commonly called Red Tide Two distinct flagella Photosynthetic Cause of harmful algal blooms The sudden multiplication of dinoflagellates Commonly called Red Tide

RED TIDES Sudden, rapid growth of dinoflagellates Poisons and kills fish- very harmful to the fishing industry. Accumulate in shellfish Toxins can be fatal: Symptoms may begin with tingling in the limbs, then paralysis of the diaphragm which leads to suffocation. Other symptoms may include amnesia, muscular paralysis, hallucinations, diarrhea, or abdominal cramps.

Brown Algae Phylum: Phaeophyta Found mostly in cold ocean water Giant kelp forests are brown algae Usually reach about 100 feet Largest: 900 feet Can regenerate their blades Found mostly in cold ocean water Giant kelp forests are brown algae Usually reach about 100 feet Largest: 900 feet Can regenerate their blades

Red Snow Caused by an algae called Chlamydomonas nivalis It is a green algae with a secondary carotenoid pigment that protects the chloroplast from UV radiation Caused by an algae called Chlamydomonas nivalis It is a green algae with a secondary carotenoid pigment that protects the chloroplast from UV radiation

Ice Cream A gum extracted from the algae called carrageenan is put in most ice creams The algae loves water- it ties up the water in the ice cream making it thick and smooth instead of thin and runny Only a half-teaspoon is used in a half gallon of ice cream A gum extracted from the algae called carrageenan is put in most ice creams The algae loves water- it ties up the water in the ice cream making it thick and smooth instead of thin and runny Only a half-teaspoon is used in a half gallon of ice cream
