1 KINGDOM PROTISTA Protists- the hodge- podge group

2 Basics  Eukaryotic  3 groups- animal like -Protozoans plant like- Algae fungi like- Slime molds Evolved from a symbiotic relationship: 1 prokaryote engulfed another (like a mitochondrial or chloroplast like cell) ENDOSYMBIOSIS

3 Protozoans- animal like HOW THEY MOVE PSEUDOPODFLAGELLACILIASPORES (SPOROZOAN) ExampleSarcodines Amoeba Zooflagellates Giardia Ciliates Paramecium Plasmodium EnvironmentSalt and fresh water 1.Streams 2. Gut of termite 3. Parasite in human DT Ponds and streams Gut of mosquito/ blood of humans Special Structures Contractile vacuole- pumps out excess water Help digest cellulose Ingest food through oral groove and gullet Macro and micronucleus Produce spores- need intermediate host like mosquito DiseasesAmoebic dysentery GiardiasisMalaria

4  Pseudopods stream in different directions to make amoeba move.  Single celled  Pseudopods surround food and engulf it

5 Giardia  Can cause giardiasis.  Usually from contaminated water.  Called backpackers diarrhea

6 Paramecium  Use cilia to sweep food into oral groove and then digest in the gullet.  Has 2 nuclei- I macro and 1 micro

7 Plasmodium  Causes malaria  Lives in gut of mosquito  Mosquito bites human  Injects some spores- they germinate and live in the blood

8 ALGAE-Plant like  Contain chlorophyll or other pigment  Can be unicellular, multicellular or colonial  7 types

9 Euglenophyte: Euglena  Unique because they can do photosynthesis and ingest food(heterotrophic).  Has an EYESPOT which helps detect light so it can swim towards it to photosynthesize  Has a flagella for movement  Pellicle- thick outer covering

10 Chrysophyte:Golden Algae  Many unicellular  Some colonial  Gold colored chloroplast

11 Diatoms  Contain chlorophyll  Photosynthetic  Shell made of SILICA- used for abrasives in cleansers like toothpaste  Also called phytoplankton

12 Dinoflagellates  Cell wall contains cellulose  Contain chlorophyll  Also have another pigment called carotenoid(orange color)  Cause Red Tide- due to overgrowth in the ocean. Produces a toxin that is harmful to sea life and humans

13 Red Algae  Phylum Rhodophyta  Multicellular  Marine sea weed  Has no roots, stems, or leaves  Main structure called a thallus  Has Chlorophyll a and phycobilins that help harvest light at deep depths.

14 Brown Algae  Phylum Phaeophyta  Multicellular  Contain chlorophyll and a brown pigment- FUROXANTHIN  Kelp  Have air bladders to keep them afloat

15 Green Algae  Phylum Chlorophyta  Most live in fresh water  Can be unicellular or multicellular Spyrogyra-multicellular  Volvox is a colonial green algae

16 Uses for Algae  Base of the food chain  Produce O  Sushi:nori  Smoothener in foods like ice cream and pudding  Industrial uses: plastics, waxes, deodorant, paint, agar( material used to grow bacteria)

17 Fungi like – Slime Molds and Water Molds  Live in moist, cool environment  Watery molds- Oomycota
