Biology Core

9. Differentiate between the previous five-kingdom and current six-kingdom classificationsystems.

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

6

Open the foldable so 2 sides show

– Copy the information on the next slide on these two sides

6

Some unicellular

• All Eukaryotic

• All live in moist environments

Protists

Others multicellular

Some heterotrophs

Others autotrophs

Most one celled microscopic

Others 300 feet long!

Animal-like

Plant-like

Two Subcategories:

Animal-like Protists • All unicellular

• Protozoans

• All heterotrophic

Subdivided: Mode of Locomotion

Pseudopodia

Cilia

Flagella

9

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 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

Amoeba

- Also used to trap food

Animal-like Protists

with Cilia

• 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.

•They also push food into the mouth area called the “oral groove”

Paramecium

Other Animal-like Protists

with Flagella • They move by beating their long whip-like structures called flagella.

• May have one or more flagella

Giardia

• Some are parasitic and cause diseases

Trypanosoma

Diarrhea

African Sleeping Sickness

Tsetse Fly

Another Disease-causing Protozoan...

Plasmodium falciparumMalaria

Female Anopheles mosquito

Plant-like Protists • Produce oxygen

• All autotrophic

• Form the base of aquatic food chainsFour basic groups:

Euglenoids

Dinoflagellates

Diatoms

• Can be unicellular, multicellular, or live in colonies

Algae

Euglena

• M

Photosyntheticext

Moves by Flagellum

Eyespot detects light so it can do photosynthesisext

Unicellular

Plant-like Protists

• Mostly unicellular, but form colonies with 1000-3000 cells living together

•Each individual cell has 2 tiny flagella that make the colony roll

Volvox

VolvoxGreen Algae

Daughter colonies will be released
