1. The Themes of Life

2. Biological Systems  Parts work together resulting in a functional system.

3. Biological Systems  Joints, muscles, brain and blood vessels = hand typing

4. Biological Systems How is a sports team a system?

5. Cellular Basis of Life  All living things are made of one or more cells.

6. Cellular Basis of Life UNICELLULAR – one cell

7. Cellular Basis of Life MULTICELLULAR – many cells

8. Cellular Basis of Life  Cell (neuron) >

9. Cellular Basis of Life  Tissues (nerve tissue) >

10. Cellular Basis of Life  Organ (brain) >

11. Cellular Basis of Life  Organ system (nervous system)

12. Form and Function How something works is related to its structure.

13. Form and Function 1.Aerodynamic shape > glide through the air 2.Honeycomb bones > strong but lightweight 3.Long extensions of nerve cells > coordinate flying movements

14. Form and Function Scooping fish from the water PELLICAN POUCH USED TO SCOOP

15. Form and Function Eating large prey GOLDEN EAGLE HOOKED FOR TEARING PREY

16. Form and Function Cracking seeds EVENING GROSBEAK SHORT, HEAVY & POWERFUL

17. Form and Function Eating nectar from a flower HUMMING- BIRD LONG & SLENDER FOR PROBING

18. Form and Function Catching insects in flight BARN SWALLOW SHORT, OPENS WIDE, CLOSES QUICKLY

19. Form and Function Probing mud for invertebrates GODWIT LONG, PINCHING, SENSITIVE TIP

20. Form and Function Eating insects taken from dead trees WOOD- PECKER STRONG & CHISEL-LIKE

21. Reproduction & Inheritance  Organisms reproduce their own kind

22. Reproduction & Inheritance  Genes (made of DNA) control traits and are passed down from parents.

23. Reproduction & Inheritance SEXUAL REPRODUCTION 1.EGG AND SPERM NECESSARY 2.CAN BE FROM THE SAME ORGANISM 3.DOES NOT REQUIRE “SEX”

24. Reproduction & Inheritance ASEXUAL REPRODUCTION Regeneration

25. Reproduction & Inheritance ASEXUAL REPRODUCTION Budding

26. Reproduction & Inheritance ASEXUAL REPRODUCTION Binary Fission

27. Interact with Environment (Response)  Organisms constantly sense and respond to a changing environment.

28. Interact with Environment (Response)  Plant takes water, nutrients, carbon dioxide and energy >> makes food  Releases oxygen, roots break up rocks, release acids, other organisms eat plants…

29. Interact with Environment (Response)

30. Energy and Life  Light energy comes from the Sun > converted to different forms of energy > used to do work > lost in the form of heat

31. Energy and Life HETEROTROPH

32. AUTOTROPH

33. Regulation / Homeostasis  Ability of organisms to regulate their internal environment to keep it in a “steady state”  BALANCE

34. Regulation / Homeostasis Panting and sweating maintain temperature homeostasis

35. Regulation / Homeostasis GLUCOSE BALANCE Increase in blood sugar is sensed by the pancreas which releases insulin. Insulin allows the cells to take in sugar and store extra for later.

36. Adaptation & Evolution  Adaptation: Inherited trait that helps the organism survive and reproduce in its environment.  Organisms are BORN with adaptations.

37. Adaptation & Evolution  Natural Selection: nature automatically allows organisms with certain traits to survive

38. Adaptation & Evolution  Evolution: process of change…change in the proportion of inherited genes in a population

39. Adaptation & Evolution What is your example of natural selection?
