Introduction to Biology Biologists make discoveries and seek explanations by performing laboratory and field investigations 4 Areas of Research Include: Diversity of Life Interactions of Life Interactions with Environment Pose Problems and Determine Solutions

Introduction to Biology Biologist spend their time studying organisms that are alive Organisms – anything that possesses the characteristics of life Characteristics of Life Include: 1. Made of one or more cells 2. Displays organization 3. Grows and develops 4. Reproduces 5. Responds to stimuli 6. Requires energy 7. Maintains homeostasis 8. Adaptations evolve over time

Characteristics of Life 1.Made of one or more cells The cell is the basic unit of life 2.Displays organization Atom Molecule Cell Tissue Organ

Characteristics of Life 3.Grows and Develops Growth results in an increase in mass Development results in different abilities 4.Reproduces Passes along genetic traits to the next generation

Characteristics of Life 5.Responds to Stimuli Reacts to internal and external changes 6.Requires Energy Energy is required for all life functions and processes

Characteristics of Life 7.Maintains Homeostasis Keeps internal environments stable 8.Adaptations Evolve Over Time Adaptations – inherited changes that occur over time that help the species survive
