- fungus like protists - 2 kinds
-
1. slime molds
2. water molds - slime molds
-
unicellular and in bad conditions join to cell multicellular groups or produce spores.
live in cool moist places or fresh water - water molds
-
unicellular
live in water, moist soil, or on other organisms
decomposers of parasites; cause of the great potato famine - fungi are:
- eukarytoc, decomposers, multicellular, hyphae and mycellum - under ground parts - assexual reproduction - spore production or hyphae break apart to form new individuals - sexual reproduction - sexual spores unite and form new fungus
- Protis are:
-
-eukaryotic
-unicellular or multicellular
-conjugation
-fission
-classified by the way they eat their food
-plants, animals, fungi evolve from protist - Plant-Like protist algae
-
1. have chlorophylp
2. multicellular algae (seaweed, kelp)
3. unicellular algae phytoplankton (oxygen) - Types of plant-like protist (GBRDDE)
-
G-green alage
B-brown alage
R-red alage
D-diatoms
D-dinoflagellates
E-euglanoids - green alage
- uni or multicellular; store starch and live anywhere chlorophyl is main pigment
- brown algae
- live in cool marine habitats have yellow-brown pigment produce algin; carb. used for food stabilizer
- red algae
- mostly multicellular store starch has chlorophyl and red pigment mainly marine; produce carrageenan:carb.used to make foods creamy
- diatoms
-
unicellular phytoplankton, marine or fresh water
cell walls made of cellulose and silica stores starch and oil - dinoflagellates
-
unicellular, mostly marine have 2 flagella
has chlorophyll and red pigment
stores starch and oil
rapid increase in population can cause red tide - euglenoids
-
unicellular, freshwater, 2 flagella has chlorophyll to make starch, but if in low light, can be a consumer and engulf food eyespot detects light
contractile vacuole collects and removes water - spore forming protist;
- parasites with two or more hosts, no cilia or flagella
- 1. amobeas
- soft, jelly-like unicellular fresh, marine , soil of as parasites in animals contractile vacuole moves with pseudopodia
- protozoa with shells
- unicelluar radiolarians-shells made of silica foraminiferars - shells made of calcium carbonate
- flagellates;
-
parasites that cause illnesses or symbiotic with animals
Example: living in guts of termites to breakdown wood - ciliates
- unicellular cilia for movement and food capture two kinds of nuclei; macronucleus and micronucleus
- animal like protist:protozoa (APFCS)
-
1. amobeas: 2. protozoa with shells;
3. flagellates; 4. ciliates
5. spore forming protist;
