Kingdom Protista

Protists- the hodge- podge group

basics
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

slide4

Pseudopods stream in different directions to make amoeba move.

  • Single celled
  • Pseudopods surround food and engulf it
giardia
Giardia
  • Can cause giardiasis.
  • Usually from contaminated water.
  • Called backpackers diarrhea
paramecium
Paramecium
  • Use cilia to sweep food into oral groove and then digest in the gullet.
  • Has 2 nuclei- I macro and 1 micro
plasmodium
Plasmodium
  • Causes malaria
  • Lives in gut of mosquito
  • Mosquito bites human
  • Injects some spores- they germinate and live in the blood
algae plant like
ALGAE-Plant like
  • Contain chlorophyll or other pigment
  • Can be unicellular, multicellular or colonial
  • 7 types
euglenophyte euglena
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
chrysophyte golden algae
Chrysophyte:Golden Algae
  • Many unicellular
  • Some colonial
  • Gold colored chloroplast
diatoms
Diatoms
  • Contain chlorophyll
  • Photosynthetic
  • Shell made of SILICA- used for abrasives in cleansers like toothpaste
  • Also called phytoplankton
dinoflagellates
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
red algae
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.
brown algae
Brown Algae
  • Phylum Phaeophyta
  • Multicellular
  • Contain chlorophyll and a brown pigment- FUROXANTHIN
  • Kelp
  • Have air bladders to keep them afloat
green algae
Green Algae
  • Phylum Chlorophyta
  • Most live in fresh water
  • Can be unicellular or multicellular

Spyrogyra-multicellular

  • Volvox is a colonial green algae
uses for algae
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)
fungi like slime molds and water molds
Fungi like – Slime Molds and Water Molds
  • Live in moist, cool environment
  • Watery molds- Oomycota
