Kingdom Protista - Mainly one celled organisms - may be producer or consumer Fungus like Protists Look and act like a Fungus ex. slime molds: can be uni-or multicellular, eat bacteria, yeast and decaying matter, form spores to reproduce. ex. water molds: can be decomposers or parasites of plants or animals caused the potato famine. Plantlike Protists (Algae) - contain chlorophyll, so are producers - most live in water or wet environments - most multicellular, like seaweed - some unicellular Green Algae - some are microscopic and make up plankton that lives in ocean. - some are seaweed, ex. sea lettuce Brown Algae - still has chlorophyll - ex. rockweed, has holdfasts that act like roots to hold it to rocks. - mostly in colder waters Red Algae - red color allows it to absorb a part of the sunlight that can penetrate deep into the ocean. - some make substances called agar, for use by scientists, and in food. - mostly in warmer waters Golden Algae - ex. Diatoms: are glass-like -when they die they form diatomaceous earth and that is used in toothpaste and scouring powder. - also used in paint to help it reflect light for road stripes. Fire Algae - also called dinoflagellates, they have 2 flagella - some cause "red tide", where they produce toxins that get in shellfish and make people sick. - some have bioluminescence "having living light" and glow in the water Euglenoids - single cell that is plant and animal like: has chlorophyll, but also has a flagella for moving.
