ANIMAL KINGDOM

Mrs. Martin

Kingdom Animalia – Complex, multi-cellular, eukaryotic heterotrophic organisms

Most complex of all kingdoms

Multicellular (made of many cells)

Obtain energy by eating food –Heterotrophic / Consumers

Usually Reproduce Sexually

•Able to move from one place to another

•Eukaryotic – cells have a nucleus but no cell wall or chloroplast

•Have Specialized Parts: Cells – Tissues – Organs - Organ Systems - Organisms

ANIMAL BEHAVIORS Innate Behavior - (NOT learned) behaviors that are influenced by genes

-an animal is born KNOWING how to do something….

(-fish – swim and birds – fly)

ANIMAL BEHAVIORS Learned Behavior - behaviors that have to be taught or observed

-Speech is innate in humans, but the language (English, French….) you speak is learned.

BODY PLANSANIMALS HAVE 3 BODY PLANS

BODY PLANS Asymmetrical – No Symmetry

Radial Symmetry – body is organized around a central point

Bilateral Symmetry – (Bi = 2) One half is exactly like the other half

ADAPTATIONS

Adaptation – a characteristic, a behavior, or any inherited trait that makes a species able to survive and reproduce in a particular environment

(include structures or behaviors for finding food, for protection, and for moving from place to place)

•Examples – Camouflage, Mimicry, Outer Coverings, ect…)

ADAPTATIONS

•lizard’s legs allow it to move on land

•polar bears fur allow it to survive in cold areas

•strawberry dart-poison frog’s bright coloring warns predators that it is poisonous

HOMEOSTASIS Homeostasis – the maintenance of a stable internal environment

Humans sweat and shiver to help maintain an internal constant temperature

Brainpop - Homeostasis
