3. What is Biology?
The study of life – Bio means “living,” and logy means “study of.”
Biology is divided into many smaller areas that focus on specialized areas of study:
Zoology – Study of Animals
Genetics – Study of Genes
Ecology – Study of Ecosystems
Cytology – Study of Cells
Botany – Study of Plants

4. Biological Studies
Lab studies – experiments done in a closed environment. Allow scientists to control all variables.
Field studies – experiments done in a natural setting. Scientists have little control over variables; however, data may be more accurate.
When would a lab study be better? A field study?

5. CHARACTERISTICS of LIFE
All living things
have these
7 things in common:
CHARACTERISTICS OF
