Kingdom Protista
The most diverse kingdom
Protist• The protist
kingdom contains the most diverse collection of organisms.
Protist• The one
characteristics all protist share is that they are all eukaryotes.
• Their cells have a nucleus and membrane bound organelles.
• List 5 organelles.
Protist• Protists can be
classified into 3 groups.
• Animal-like: they are heterotrophs
• Plant-like: they are autotrophic
• Fungus-like: they are decomposers
Protozoa• Animal-like protists
are call protozoa• All are unicellular• All are heterotrophs• All are aquatic• Reproduce asexually• Protozoa:
Enoploplastron triloricatum
Protozoa• Classified by they
way they move• Cilliates: protozoa
covered by hairlike structures
• Paramecium
HeterotrophicDidinium eating a
Paramecium•
Protozoa• Flagellates- use
whiplike flagella to move
Protozoa• Amoeba- move by
sending out pseudopodia (false feet) and oozing around
Protozoa• Sporazoans-
produce spores• All are parasites• Plasmodium lives
in mosquitos and causes malaria
Algae• Plant-like protist
are called algae• Both unicellular
and multicellular• All are autotrophs
Algae• Algae can be
classified into six groups
• The euglenoids, diatoms and dinoflagellates are all unicellular
Algae• The multicellular
algae can be classified as green, red, or brown
Spyra Gyra•
Kelp•
Dynoflagellate•
Euglena with red eyspot•
Molds and Mildews• Fungus-like
protists are the water molds, downy molds and slime molds
Mold and Mildews• All molds and
mildews are decomposers
Mold and Mildews• Slime molds have
the characteristics of both protozoans and fungus-like protists.
• During part of their life cycle they are mobile.
