Fungus like Protists # 5 All fungus like protists are Heterotrophs. They have cell walls like a plant. They use Spores to reproduce. They are able to move at some point in their lives. The three types of Protist are: Water molds, Downy mildew and slime molds. Water molds and Downy mildew: Live in water and moist places. . These organisms grow as tiny threads that look like a fuzzy covering. Downy mildew and water molds also attack food crops. Slime mold: Live in moist soil and on decaying plants and trees. They are beautifully colored. They move in an ameba like way by forming pseudopods. They feed on Bacteria and other microorganisms. During unfavorable conditions, they form a multicellular mass. Spore producing structures grow out of the mass and release spores which can develop into a new generation of slime molds. Plant like Protist (Algae) # 6 All algae share common characteristics with plant: they are autotrophs. Some algae live in soil, some on the barks of the tree while others in salt water and still others in fresh water. They are an important source of food for other organisms. Majority of the earth’s oxygen is made by these algae. Algae’s come in variety of sizes. Some are unicellular, some are multicellular. Sometimes unicellular algae come together to form colonies. In that case, some cells become specialized to do certain tasks. They come in variety of pigments. Below is the list of different algae’s and their characteristics. Eugleniod Diatoms Unicellular Unicellular Dinoflagellate s Unicellular Green ,found in fresh water Autotrophs and turn to heterotrophs when sunlight is not available Flagellum and a eyespot Fresh water, Saltwater Autotrophs Variety of colors Autotrophs Glasslike Cell wall covered by stiff plates Forms diatomaceous earth: a good polishing agent. Added to toothpastes, used as swimming pool filters, insecticides, and household scouring products. Green Algae Red algae Unicellular, Colonies, Multicellular Green, freshwater, salt water Autotrophs Multicellular Multicellular Oceans Autotrophs Brown Algae Cool, rocky waters Autotrophs Sea weeds Contains variety of pigments, has plant like structures. Carrageenan substance extracted from algae is used in ice creams and hair conditioners. Algins extracted from algae used in thickeners in food. Used as nutrients.
