Biology Core
9. Differentiate between the previous five-kingdom and current six-kingdom classification
systems.
Objective B.9.5: Differentiate among the major characteristics of the six
kingdoms.
Additional content to be taught:
Identifying ways in which organisms from the Monera, Protista, and Fungi kingdoms are
beneficial and harmful
Examples:
beneficial—decomposers,
harmful—diseases
• Writing scientific names accurately by using binomial nomenclature
11. Classify animals according to type of skeletal structure, method of fertilization and
reproduction, body symmetry, body coverings, and locomotion.
Examples:
reproduction—sexual, asexual;
locomotion—cilia, flagella, pseudopodia
Objective B.11.2: List types of body coverings and locomotion found in
animals.
Objective B.11.5: Describe the types of reproduction as asexual or
sexual..

For your foldable
• 1. Fold your paper in half -hamburger
fold-then in half again....to make a booklet
• 2. On the front... Write as shown on the
next page:
•Protist...
•
the Outcast!
4
Protists
The Outcasts
Open the foldable so
2 sides show
–
Copy the
information on the
next slide on these
two sides
6
Protists
Some unicellular
Others multicellular
Some heterotrophs
Others autotrophs
Most one celled
microscopic
Others 300 feet long!
• All Eukaryotic
• All live in moist
environments
Two Subcategories:
Animal-like Protists
• Protozoans
• All unicellular
• All heterotrophic
Subdivided: Mode of Locomotion
Pseudopodia
Cilia
Flagella
Open foldable all the way so 4
boxes show
• The top two boxes will show animal like
protist (protozoans).... amoeba and
paramecium
• The bottom two boxes will show plant like
protist.... euglena and volvox
• Draw the simplified pictures on the chart
paper and label the parts then copy the
9
info on the next slides
Animal-like Protists
• They move by extending a
part of their body forward, and
pulling the rest of its body
behind it
• Pseudopodia – finger-like
projections that extend outward
- Also used to trap
food
Amoeba

Animal-like Protists
• They move by beating tiny
hair-like structures called cilia
• The cilia act as tiny oars that
allow the protist to move through
its watery environment.
Paramecium
•They also push food into the
mouth area called the
“oral groove”
with Cilia
Other Animal-like
Protists
with Flagella
• They move by beating their
long whip-like structures called
flagella.
• May have one or more flagella
• Some are parasitic and cause
diseases
Giardia
Tsetse Fly
Diarrhea
Trypanosoma
African Sleeping Sickness
Another Disease-causing
Protozoan...
Female Anopheles mosquito
Plasmodium falciparum
Malaria
Plant-like Protists
Four basic groups:
Euglenoids
Dinoflagellates
Diatoms
Algae
• All autotrophic
• Produce oxygen
• Form the base of
aquatic food chains
• Can be unicellular,
multicellular, or live in
colonies
Euglena
• M
Photosynthetic
ext
Unicellular
Moves by Flagellum
Eyespot detects light
so it can do
photosynthesisext

15
Plant-like Protists
Volvox
Green Algae
Volvox
• Mostly unicellular, but form
colonies with 1000-3000 cells
living together
•Each individual cell
has 2 tiny flagella that
make the colony roll
Daughter colonies will be
released
