1. Properties of Life 1.1
AP Biology
Mini Lecture

2. Biology—the scientific study of living things
“Living things”—All the diverse organisms descended from a single-celled ancestor (a single common ancestor)
All organisms come from 3 Domains
Archaea – special living bacteria
Bacteria – regular normal everyday bacteria
Eukarya – all eukaryotes (Protists, Fungi, Plants and Animals)

3. Characteristics of Life – for all organisms for all domains
Order - all life have common chemical components (DNA etc.) and a cell
Energy Processing - metabolism, cellular respiration
Homeostasis - regulate internal environment
Response to the environment - respond to stimulus
Reproduction - replicate genetic information
Growth and Development - grow into adults, cellular specialization
Evolutionary Adaptation- change due to environment and gradual changes in genes

5. Chloroplasts and Mitochondria
Endosymbiotic Theory
It holds that the organelles  evolved from symbiosis of individual single-celled prokaryotes
 are thought to represent formerly free-living prokaryotes 
One piece of evidence is that both organelles have their own DNA!
