1. What are the two bacterial
kingdoms?
2. Explain the difference between the
two kingdoms listed in #1.

What is the Difference Between
Prokaryotic and Eukaryotic?
2.
1. Prokaryotic
Prokaryotic cells
cells lack
havemembrane-bound
no nucleus;
organelles
Eukaryoticsuch
cellsas
doa 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
Reproduction:
Binary Fission
(Asexual)*
-One parent
-Doesn’t exchange
DNA
-Produces identical
offspring
Reproduction:
Conjugation(Se
xual)*
Two parents
Exchange DNA
Produce different
offspring
Zooplankton: Amoeba
Amoeba Structure
Amoeba are unicellular

Amoeba
Information*
Move using
Pseudopod –
False foot
Literally
moves like a
blob
Method of Feeding*
Heterotroph
Watch Video: Click picture
Pseudopod
surrounds food;
process called
Phagocytosis
Eventually
engulfs it

Reproduction: Binary Fission
(Asexual)
-One parent
-Doesn’t
exchange
DNA
-Produces
identical
offspring
Protozoa: Plant-like Protists
AKA: 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
Watch Video: Click picture
*They can spin like a tornado
Watch Video: Click picture
*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
Reproduction:
Binary Fission
(Asexual)
-One parent
-Doesn’t
exchange DNA
-Produces
identical
offspring
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

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 Algae
Unicelluar; 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≠Leaf
Stipe≠Stem
Holdfast≠Roots
Seaweed is an example of Brown Algae
Kelp is also an
example of Brown
Algae
Brown Algae is Edible
