Protist Kingdom
What is the Difference Between Prokaryotic and Eukaryotic?
1. Prokaryotic cells have no nucleus; Eukaryotic cells do
2. Prokaryotic cells lack membrane-bound organelles such as a mitochondria and chloroplast; Eukaryotic cell have them.
Protist Habitat: Freshwater (ponds, rivers, streams, etc)
Protist Habitat: Marine (Ocean)
Protist Habitat: Soil
Protist Habitat: In other organisms
Protozoa: Animal-like Protists
AKA: Zooplankton
Zooplankton: Paramecium
Paramecium Structure
Paramecium are unicellular
Paramecium Information*
Move using Cilia – tiny
hairs covering the outermost
layer
Paramecium Information
ALL aquatic protists contain a
contractile vacuole
Acts like a water pump which regulates the
water pressure inside organism
*
Method of Feeding*
Heterotroph
Cilia helps guide food into the gullet; a food
vacuole is formed;
digestive enzymes break
down food
-One parent-Doesn’t exchange
DNA
-Produces identical offspring
Reproduction: Binary Fission (Asexual)*
Reproduction: Conjugation(Se
xual)*
Two parentsExchange DNA
Produce different offspring
Zooplankton: Amoeba
Amoeba Structure
Amoeba are unicellular
Amoeba Information*
Move using Pseudopod –
False food
Literally moves like a
blob
Method of Feeding*
Heterotroph
Pseudopod surrounds food; process called Phagocytosis
Eventually engulfs itFast forward to 1:15
-One parent-Doesn’t exchange DNA
-Produces identical offspring
Reproduction: Binary Fission (Asexual)
Protozoa: Plant-like ProtistsAKA: Phytoplankton
Phytoplankton: Euglena
Euglena Structure
Euglena are unicellular
Euglena Information
Move using a Flagella; a long
whip-like tail
Different species of
euglena move in different ways
*They can spin like a tornado
*They can move like a worm
Method of Feeding
Autotroph and Heterotroph
Can undergo photosynthesis;
has an eyespot to act as a sunlight
sensor
Also can consume food if necessary
-One parent
-Doesn’t exchange DNA-Produces identical offspring
Reproduction: Binary Fission
(Asexual)
Phytoplankton: Dinoflagellates
Dinoflagellates are Unicellular
Some have the ability to
bioluminescence (glow)
The ability to glow is similar to a burglar alarm
or defense system
Video #1: Splashing Water (Turn Volume Down)
Video Clip #2: Surfing
Phytoplankton: Diatoms
Diatoms are Unicellular
-Diatoms cell wall contains silica (glass)-When they die their silica shells fall to ocean floor. It becomes diatomaceous earth
Phytoplankton: Green AlgaeUnicelluar; Multicellular; Colonial (many individual organisms living together in a
outer membrane)
Most diverse group of protists; can be found everywhere
Even on the backs of some animals
Phytoplankton: Brown Algae
Not a true plant because it
lacks TRUE roots, stems,
and leaves
Frond≠LeafStipe≠Stem
Holdfast≠Roots
Seaweed is an example of Brown Algae
Kelp is also an example of Brown
Algae
Brown Algae is Edible
