1. Introduction to Biology
Bio-= Life
-logy- Study of
Biology- Study of Life

2. Types of Life

3. 5 Characteristics of Life
Cells- most basic unit of life.
(Organization)
Ex. Animal, Plant, Bacteria

4. 2. Energy Animals Plants Eat Food Collect Sunlight Cell Respiration
Photosynthesis

5. 3. Respond to Environment
React to external stimuli
Example: Birds Migrate, Shivering in Cold

6. Homeostasis Maintenance of a stable internal environment. Temperature
Heart Rate
Breathing

7. 4. Grow and Develop
Start at a small size and grow larger and develops in order to survive. Changes over time.
Example-
1. Baby -> Adult
2. Seed -> Plant

8. 5. Reproduction- create new living organisms
Asexual
1 parent/ 2 identical offspring
Sexual
2 parents/ 1 genetic different offspring
Combination of sperm & egg

9. 5 Characteristics of Life
Cells
Energy
Respond to Environment
Grow and Develop
Reproduce
THESE ARE NOT CHARACTRISTICS OF ALL LIFE
MOVING
BREATHING
EATING
DANCING

10. Levels of Biology Micro- = small Biochemistry- atoms, bonds, molecules
Cell Biology-parts & function of cell
Genetics- heredity
Macro- = Large
Evolutionary theory
Ecology- organisms relating to one another
Botany- study of plants
Zoology- study of animals

11. Fields of Biology
Anatomy - The study of body parts and their locations (ana = up, tom = to cut)
Physiology - The study of how various body parts function (physio = nature)

12. Botany - The study of plants (botan = grass, pasture)
Cytology - The study of cells (cyto = cell)
Ecology - The study of the interrelations between organisms and their environment (eco = house)

13. Genetics - The study of genes and heredity (gene = origin, birth)
Microbiology - The study of bacteria and other microscopic organisms (micro = small)
Zoology - The study of animals (zoo = animal)
