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 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
