Introduction to BiologyIntroduction to Biology• Biology – the study of life

• Biologists study:• Origins and history of life• Structures of living things• How living things interact

with one another• How living things function

Introduction to BiologyIntroduction 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 BiologyIntroduction 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 LifeCharacteristics of Life3. 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 LifeCharacteristics of Life5. Responds to Stimuli

• Reacts to internal and external changes

6. Requires Energy• Energy is required

for all life functions and processes

Characteristics of LifeCharacteristics of Life7. Maintains Homeostasis

• Keeps internal environments stable

8. Adaptations Evolve Over Time

• Adaptations – inherited changes that occur over time that help the species survive
