5. What is biology? Who studies biology?
Biologists = individuals that study living things.

6. How do you know if something is living?

7. 5 Major Characteristics of Life
Organization
Reproduction
Growth and Development
Metabolism
Adaptation

8. Organization How is your body organized?
Do the parts of living organisms mean anything?
What do they do?
What are they made of?

9. Organization
Living things have specialized parts that perform specific functions
These parts are composed of cells

11. Organization Cell = the basic unit of life
An object cannot be living unless it is composed of one or more cells!
Unicellular = living things composed of ONE cell
Multicellular = living things composed of more than one cell

12. Is this organism unicellular or multicellular?

13. Is this organism unicellular or multicellular?

14. Is this organism unicellular or multicellular?

15. Reproduction Why do living things need to reproduce?
Reproduction= making more of an organisms
Essential to the continuation of a species
Species = a group of similar organisms that are able to interbreed AND produce fertile offspring

16. Is a mule a species?

17. …what about a Liger?

18. Species v. Hybrids
Species = organism that can interbreed AND reproduce with fertile offspring
Examples:
Lion
Tiger
Horse
Donkey
Hybrid = organism produced by interbreeding of two different species that is infertile
Examples:
Liger
Mule
Zonkey

19. Growth and Development
How have you changed since birth?
Do other organisms change after birth?
How do growth and development differ?

20. Growth Growth = increasing the amount of living material
Getting bigger by adding more cells

21. Development
Development = formation of physically different structures

22. How do organisms get energy?
Organisms must “eat” something
What an organism eats and how it uses that energy is called a metabolic pathway
Metabolism = using energy from food to carry out cellular processes (foodenergy)

23. What do you think each of these organisms use for food?

24. Adaptation Why do organisms need to adapt?
What causes them to adjust to their surroundings?

25. Adaptation
Stimuli = changes in an organisms’ environment that cause a response
Response = reaction to a stimulus

26. Adaptation and Homeostasis
Adjusting helps maintain homeostasis
Homeostasis = maintaining internal balance in a changing environment

27. Cells Maintain Homeostasis too!

28. Create a Concept Map that organizes the 5 characteristics of living things AND uses these terms…
Cell
Specialized parts/functions
Unicellular
Multicellular
Species
Hybrid
Grow(th)
Development
Metabolism
Stimuli
Response
Homeostasis
