2. Introduction to Biology  Objectives:  Define Biology  What “other sciences” involve Biology  Describe characteristics of living things  List and explain six kingdoms of biology.

3. Biology Biology- Study of all living things  40 million organisms- 2 million have been identified

4. Branches of Biology  Ecology-study of living organisms and their interaction with their environment’  Zoology- Study of animals.  Entomology- Study of insects  Botany- Study of Plants  Anatomy- Study of the body

5. 6 kingdoms 1.Plants 2.Eubacteria 3.Archeabacteria 4.Protista 5.Animalia 6.Fungi

6. What does it mean to be living?

8. Characteristics of Living Things 1. Made of cells a. Unicellular: one-celled b. Multicellular: Many celled c. Many different types of cells 2. Use Energy a. Metabolism: sum of all of the chemical processes that occur in the organism: (digestion, ingestion, egestion) 3.Homeostasis: Maintain stable internal conditions. ie: temperature and water

9. Characteristics of Life Con’t 4.Grow and Develop a. Increase in cell size and cell number 5.Reproduction a. Necessary for species to continue b. sexual: involves union of gametes, genetically different asexual: does not involve the union of gametes, genetically same

10. Characteristics of Living Things Con’t 6.Heredity: Pass characteristics or traits from one generation to the next. a. Genes: sets of inherited instructions for making proteins b. DNA: Deoxyribonucleic acid- determines traits c. Mutations: a change in the DNA of a gene 7.Adapt a. Organisms have evolved or adapted to live and interact with their environments and other organisms.
