10. 2) Reproduction Reproduction – The process by which genetic information is transferred from parent to offspring –Asexual: Genetic information is not combined (splitting bacteria) –Sexual: Genetic information is combined

11. 2) Reproduction Reproduction – The process by which genetic information is transferred from parent to offspring –Asexual: Genetic information is not combined (splitting bacteria) –Sexual: Genetic information is combined

14. 2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Sexual Reproduction

15. 2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Sexual Reproduction

16. 2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Inheritance: Acquiring traits from parent to offspring Sexual Reproduction

17. 2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Inheritance: Acquiring traits from parent to offspring

18. 2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Inheritance: Acquiring traits from parent to offspring

19. 2) Reproduction Inheritance: Acquiring traits from parent to offspring DNA – Genetic information molecule –Gene : Segment of DNA. Chemical message for a certain trait Sexual Reproduction

20. 2) Reproduction DNA – Genetic information molecule –Gene : Segment of DNA. Chemical message for a certain trait

21. 2) Reproduction DNA – Genetic information molecule –Gene : Segment of DNA. Chemical message for a certain trait

22. 3) Development Development – Process where a fertilized egg (zygote) becomes a mature individual. Life cycles of organisms

23. 3) Development Development – Process where a fertilized egg (zygote) becomes a mature individual. Life cycles of organisms –Unicellular: “one” celled –Multicellular: “many” celled

24. 3) Development Development – Process where a fertilized egg (zygote) becomes a mature individual. Life cycles of organisms –Unicellular: “one” celled –Multicellular: “many” celled

28. 5) Energy Relationships Energy Relationships – How is energy converted, stored and used

29. 5) Energy Relationships Energy Relationships – How is energy converted, stored and used Autotrophs – “self- feeders” – plants and some unicellular organisms. Acquire energy by making their own food (photosynthesis)

30. 5) Energy Relationships Energy Relationships – How is energy converted, stored and used Autotrophs – “self- feeders” – plants and some unicellular organisms. Acquire energy by making their own food (photosynthesis)

31. 5) Energy Relationships Autotrophs – “self-feeders” – plants and some unicellular organisms. Acquire energy by making their own food (photosynthesis) Heterotrophs – “other-feeders” – animals, fungi and some unicellular organisms. Acquire energy by eating other organisms

32. 5) Energy Relationships Autotrophs – “self-feeders” – plants and some unicellular organisms. Acquire energy by making their own food (photosynthesis) Heterotrophs – “other-feeders” – animals, fungi and some unicellular organisms. Acquire energy by eating other organisms

33. 5) Energy Relationships Autotrophs – “self-feeders” – Heterotrophs – “other- feeders” – Metabolism – The sum of all the chemical processes that happen in an organism

34. 5) Energy Relationships Metabolism – The sum of all the chemical processes that happen in an organism Homeostasis – The ability of an organism to keeps its internal conditions the same as environmental conditions change.

35. 5) Energy Relationships Metabolism – The sum of all the chemical processes that happen in an organism Homeostasis – The ability of an organism to keeps its internal conditions the same as environmental conditions change.
