Chapter 20

! II. ANIMAL – LIKE PROTISTS "  Heterotrophic "  Reproduce by binary fission or conjugation

!  A. Phylum Zoomastigina Pg. 499 #  Animal – like protists that move using flagella

#  Aka zooflagellates

!  B. Phylum Sarcodina pg. 500 #  Move using pseudo pods (false feet) #  Amoeba #  Heliozoans – “sun animals” #  Formaniferans – shell made of calcium carbonate

! C. Phylum Ciliophora pg. 501 "  Use cilia for movement and feeding

! D. Phylum Sporozoa pg. 503

"  Parasitic, do not move on their own "  Need a carrier such as an insect, human, birds "  Cause Malaria, African Sleeping sickness, and

Amebic dysentery

! A. Phylum Euglenophyta pg. 507 "  Have 2 flagella "  Eyespot – cannot form images, used to detect

sunlight ! B. Phylum Bacillariophyta pg. 507

"  Diatoms "  Shaped like a Petri dish "  Thin, delicate cell walls made of silicon (makes

glass) ! C. Phylum Rhodophyta pg. 510

"  Red Algae "  Multicellular "  Absorbs blue light and can live at great depths

! D. Phylum Phaeophyta pg. 511 "  Brown algae "  Giant kelp = 60 meters tall

! E. Phylum Chlorophyta pg. 512 "  Green Algae "  Unicellular, colonial, or multicellular

! F. Human Uses of Algae "  Treat stomach ulcers, high blood pressure and

arthritis "  Sushi, ice cream, salad dressing, pudding "  Agar "  Plastics, waxes, deodorant, paints, lubricants

Chapter 21

! Eukaryotic, heterotrophic, have cell walls made of chitin

! All multicellular, except for yeasts ! Feed by digesting food outside their body

and then absorbing it ! Most reproduce sexually and asexually

"  Asexual – cells break off and begin to grow on their own

"  Sexual – involves 2 different mating types

! Based on method of reproduction and their structure

! 4 main groups: "  Common molds "  Sac fungi "  Club fungi "  Imperfect fungi

! Recycle nutrients through the ecosystem ! Break down dead / decaying matter ! Parasitic – cause human and plant diseases

"  Exp: athletes foot

! Symbiotic relationships "  Lichens – algae and fungus "  Mycorrhizal – fungus and plant roots
