INTRO TO

THE ANIMAL

KINGDOM

What is an Animal? Characteristics of All Animals

1. Animals are Multicellular

2. Animals are Eukaryotic

3. Animals are Heterotrophs

4. Animal cells lack cell walls

Evolutionary/Developmental Milestones in Animals

1. Cell specialization and levels of

organization

2. Development of body symmetry and

segmentation

3. Development of an internal body cavity

and tissue layers

Cell Specialization

Cells throughout a multicellular organism can develop in different ways

to perform different tasks.

Levels of Organization

Body Symmetry (3 Types)

1. Radial Symmetry:A body plan in which all body parts of an organism are arranged around a central point

Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry…

Body Symmetry

2. Bilateral Symmetry:a single plane divides the body into two mirror images

Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry…

Body Symmetry

3. Asymmetry:cannot be divided into mirror images

Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry…

Body Segmentation

Segmentation of the body allows development of various specialized limbs, such as antennae, pincers, walking legs, claws, wings, etc.

Body Segmentation

Cephalization is the concentration of nervous tissues in one location which eventually produces a head region with sensory organs and a brain.

Tissue Layers & Body Cavity

A body cavity, called a coelom, increases the efficiency of food intake and waste

removal.

Tissue Layer Develops Into

Endoderm digestion and respiration structures

Mesoderm muscles, bones, blood, skin, reproductive organs

Ectoderm skin, brain, nervous system

The Animal Kingdom is divided into two main groups…

ANIMAL BODY SYSTEM FUNCTIONS

Body systems are all interrelated and work together to perform their functions in animals. Body systems can be organized and studied by these four functions:

➢1. REGULATION: Excretory & Nervous Systems

➢2. NUTRIENT ABSORPTION: Respiration, Digestion, & Circulatory Systems

Body systems are all interrelated and work together to perform their functions in animals. Body systems can be organized and studied by these four functions:

➢3. DEFENSE: Immune, Integumentary, Lymphatic, Skeletal, & Muscular Systems

➢4. REPRODUCTION: Reproductive & Endocrine Systems
