4. What is biology? Greek word Bios = life Logy = study of
Organisms are complex and vary – biologists work can vary greatly

5. Made up of cells Cell Unicellular Multicellular
Small, self contained units
Smallest units of an organism that can be considered alive
Unicellular
Multicellular

6. Reproduction Sexual reproduction Asexual reproduction
2 cells from different parents unit to produce the 1st cell of organism
Asexual reproduction
Single celled organism divides in half
A portion of an organism splits off to form a new organisms

7. Based on a Genetic Code Offspring always resemble parents
Asexual – offspring and parents have same traits
Sexual – offspring differ in some ways
Flies always produce flies, dogs always produce dogs, etc
Deoxyribonucleic acid

8. Growth & Development Each organism has a distinctive life cycle
Some microorganisms – main change is growth
Development
Eggs -> maggots -> flies
Cells increase in number & differentiate

9. Need for Materials & Energy
Survival & growth
Metabolism = combination of chemical reactions through which an organism builds up or breaks down materials in life processes
Plants, algae, and some bacteria
Photosynthesis – sun energy
Most other organisms
Rely on energy stored during photosynthesis
Consume those organisms
Decomposers
Obtain energy from remains of organisms that have died

10. Response to the Environment
Organisms live in constantly changing environments
Light, temperature, etc.
Each organism responds to these changes in its own way

11. Maintaining Internal Balance
Changes in an organism are complex.
Homeostasis – the process by which organisms keep their internal conditions relatively stable.
If homeostasis is disrupted in a major way, the organism cannot survive.

12. Evolution Evolve Change over time
Over a few generations – changes don’t seem significant and are typically very small.
Over hundreds of thousands of years, changes can be dramatic

13. Branches of Biology Zoologists Zoo = animal Botanists
Botanikos = plants
Ethologists
Ethos = custom
Paleontologists
Paleo = ancient

15. What are ALL 8 characteristics of living organisms?
Made of cells
Reproduce
Universal genetic code
Grow and develop
Obtain and use materials and energy
Respond to their environment
Maintain stable internal environment
Change over time

16. Pg. 30 – Due beginning of next class
Define vocabulary for 1-3
Answer questions 1, 2, 3, 8, 9, 21, 22
You do not need to write out full question.
Answer questions as full sentences.
It should be short answer. You should be able to read questions later and understand.
8 characteristics of living organisms

17. Pillbug Lab We need pillbugs!
You should collect them in some type of plastic container. Poke holes on top and place vegetation inside.
We will begin this lab September 5, 2017

18. Recap What are the 8 characteristics of living things?
What is homeostasis?
