2.  Taxonomy is the science of classifying organisms.  Scientific names is based on the taxonomy of an animal species. Each animal has a two part name. (Genus and Species)  Common name is the name of everyday conversation.  Kingdom animalia share three traits  Animals are made up of cells  Animals can move about on their own  Animals get their food form other sources

3.  Animals are classified into two groups:  Vertebrate – an animal with a backbone  Invertebrate - an animal without a backbone

4.  Animals are classified into three main classes:  Birds – feathers, light bones,  Fish – Scales, breathe through gills  Mammals – mammary glands, females produce milk, have hair, teeth, 4- chambered heart, regulated body temperature.

5.  Animal life needs are  Getting and using food  Movement  Circulation  Respiration  Growth and repair  Secretion  Sensation  Reproduction

6.  Cell Division – Mitosis and Meiosis  Cell Specialization – Tissue and Organs

8.  The five shapes of bone are:  Short – cubed shaped  Flat - skull  Irregular – complex with varying shapes  Sesamoid – small and embedded in tendons (small)  Long - longer than wide - legs

9.  Cartilage – rubbery tissue found at ends of long bones and between vertebrates  Growth Plates – place where cartilage is formed in layers. These layers become bone and new layers of cartilage is formed. Repeats until adulthood.  Marrow – yellow ( mostly fat) and red ( network of blood vessels and blood forming cells.

10.  Muscular System  Skeletal System  Digestive System  Respiratory System  Circulatory System  Excretory System  Lymphatic System  Nervous System  Integumentary System  Reproductive System
