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

3. Homeostasis– Living things can maintain internal conditions. Example: When hot, dogs sweat to cool themselves down.Slide5

4. Response to the environment– Living things will respond to stimuli in the outside world. Example: Plants will grow toward the light.Slide6

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
