Kingdom PROTISTA

1
Kingdom PROTISTA

• Protozoans
• Algae

2
General Characteristics

• All are either unicellular or colonial.
• None produce true tissues.
• Contain approximately 125,000 different
  organisms.
• Divided into two major groups protozoans algae
  (not part of the classification system)

3
Protozoans

• microscopic, unicellular, motile organisms
• most are aquatic many are found in the soil
• large number are parasitic
• most obtain food from other sources, some can
  make their own food

4
Algae

• every natural water supply contains some type of
  algae
• most are microscopic unicellular or colonial
  organisms (some reach 100 feet)
• they may appear to be floating mats of green
  slime or velvety coatings on submerged rocks
• most make their own food - by photosynthesis

5
Protozoans are divided into two phyla based on
their means of locomotion

• Phylum Ciliophora - ciliates
• Phylum Sarcomastigophora amebas,
  sarcodines, flagellates

various pigments they contain

• Phylum Chrysophyta - golden-brown algae,
  yellow-green algae, diatoms
• Phylum Chlorophyta - green algae
• Phyium Phaeophyta - brown algae
• Phylum Rhodophyta - red algae
