Order – All life is organized from simplest atoms to the organism. Example: Bacteria are unicellular and aren’t as complex as humans which have tissues and organs.Slide3

2. Energy Processing – Energy is transferred from 1 form to another form in living things. Example: Trees do photosynthesis and convert light energy to chemical energy.Slide4

5. Reproduction– Living things are capable of producing like organisms at some point in their life cycle. Example: Birds will lay eggs that will hatch into baby birds. Slide7

6. Growth & Development – Living things grow (increase in cells) and develop into adults. Example: Babies get bigger and become adults.Slide8

7. Evolutionary Adaptation– Living things evolve by adapting to their environments. Example: Peppered Moth population turned more black in color due to the industrial revolution.Slide9
2. Evidence that life had a single origin
The properties of life
All life shares these properties which leads us to the conclusion that there is one common ancestor for all living things.Slide10
3. Timeline and Significance
Age of Earth - ~4.6 billion years ago
Significance – Allows scientists to date fossils
Chemical Evolution - ~3.8 billion years ago
Significance – Allows proteins and nucleic acids to form, which is part of lifeSlide11
3. Timeline and Significance
Evolution of Cellular Structure and Prokaryote Cell - ~3.5 billion years ago
Significance – Allowed first reproducing cellular organisms to form
Photosynthesis - ~2.7 billion years ago
Significance – Provided oxygen and allowed life to move on landSlide12
3. Timeline and Significance
Appearance of Eukaryotes and Multicellularity- ~3.5 billion years ago
Significance – Allows specialized cellular functions to be performed away from the rest of the cell and
Allowed specialization of tissuesSlide13
4. Why is classification of living organisms necessary to understanding biology?
There are tens of millions of species that exist on Earth
Giving each a name allows for organization and to compare for an evolutionary context.Slide14
5. What are the 3 domains? What are the major groups of eukaryotes?
Domains
Archaea – unique prokaryotes
Bacteria – regular prokaryotes
Eukarya - eukaryotesGroups of Eukaryotes
Plants
FungiAnimalsProtistsSlide15
6. What are the origins of chloroplasts and mitochondria in eukaryotes?
They originated by endosymbiosis – when larger cell’s ingest smaller ones.
Mitochondria probably evolved from engulfed prokaryotic organisms
Chloroplasts probably evolved from engulfed photosynthetic prokaryotes
