Biology Biology – The study of life Organisms – all living things
Biology Biology – The study of life Organisms – all living things 7 major themes: 1) Evolution 2) Reproduction 3) Development 4) Structure and Function 5)Energy Relationships 6)Ecology 7)Science and Society
1) Evolution Evolution - The process where species change over time –Adaptations: Favorable traits which allow organisms to survive in specific environments –Phylogeny: Evolutionary history of groups of organisms

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
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
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 Asexual Reproduction
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 Sexual Reproduction
2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Sexual Reproduction
2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Sexual Reproduction
2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Inheritance: Acquiring traits from parent to offspring Sexual Reproduction
2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Inheritance: Acquiring traits from parent to offspring
2) Reproduction –Sexual: Genetic information is combined Sperm + Egg = Zygote (fertilized egg) Inheritance: Acquiring traits from parent to offspring
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
2) Reproduction DNA – Genetic information molecule –Gene : Segment of DNA. Chemical message for a certain trait
2) Reproduction DNA – Genetic information molecule –Gene : Segment of DNA. Chemical message for a certain trait
3) Development Development – Process where a fertilized egg (zygote) becomes a mature individual. Life cycles of organisms
3) Development Development – Process where a fertilized egg (zygote) becomes a mature individual. Life cycles of organisms –Unicellular: “one” celled –Multicellular: “many” celled

4) Structure and Function Morphology – Structure and form (Anatomy – internal structure) Function – How structures work (Physiology)
4) Structure and Function Morphology – Structure and form (Anatomy – internal structure) Function – How structures work (Physiology)
5) Energy Relationships Energy Relationships – How is energy converted, stored and used
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)

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

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

6) Ecology Ecology – Interactions of organisms with each other and their environment
6) Ecology Ecology – Interactions of organisms with each other and their environment –Biosphere – all living things on earth –Biodiversity: the variety of species of living things found on earth
