Presentation Transcript

  1. Gen Bio II Dr. Diane Cleverley

  2. Diane Cleverley, PhD • Molecular Genetics and Microbiology • 15 years teaching experience • 13 years experience in medical communications

  3. Class Elements Lecture: TR – 10:30PM – 11:50PM; Laboratory: R – 1:30PM – 4:20PM • Homework- work through the study guide ( you do NOT need to hand in) • Pre-read lab for the week • Quizzes on Lectures and Lab • 4 Major exams

  4. Definition • Biology: The study of living organisms

  5. Gen Bio I Review: • Chemicals of Life: Carbon, Hydrogen, Oxygen, Nitrogen • Macromolecules: DNA, RNA, proteins, carbohydrates • The Cell: organelles, membranes

  6. Inside the Cell • Enzymes • Cellular Respiration (the Citric Acid Cycle) • Photosynthesis (The Calvin Cycle) • DNA>>RNA>>protein • Transcription, Translation

  7. Cell Division • Mitosis • Cell Cycle • 4 phases of mitosis • Meiosis • How it differs • Haploid vs. Diploid

  8. Learning Objectives • Compare and contrast the characteristics of the five kingdoms of living organisms • Demonstrate the concept of binomial nomenclature

  9. So what is next? • Moving up in organization • Cells: • Single celled organisms: bacteria, algae, yeasts • Multicellular organisms: fungi, plants, animals

  10. How would you classify organisms? • Morphology • Development • Geography • Any other ways?

  11. First attempts • Plant • Animal • Bacteria

  12. The Five Kingdoms All living things are placed into one of the five kingdoms listed below. 1. Monera • Protista • Fungi • Plantae 5. Animalia

  13. The Five Kingdoms All living things are placed into one of the five kingdoms listed below. 1. Monera • Protista • Fungi • Plantae 5. Animalia

  14. Monera Kingdom The major characteristics of the organisms in this kingdom are: • They are unicellular organisms. 2. They do not have a nucleus.

  15. Protista Kingdom The major characteristics of the organisms in this kingdom are: • They are unicellular organisms. 2. They have a well defined nucleus.

  16. Fungi Kingdom The major characteristics of this kingdom are: 1. They can be either unicellular or multicellular. 2. They do not contain chlorophyll. 3. Their cell wall is different from a plant cell wall.

  17. Plantae Kingdom The major characteristics of this kingdom are: 1. They can be unicellular or multicellular. 2. They are autotrophs because they can make their own food.

  18. Animalia Kingdom The major characteristics for this kingdom are: • They are multicellular. 2. All are heterotrophs because they can not make their own food.

  19. Identify the Kingdom I am a unicellular organism with a nucleus. What kingdom do I belong to? • Monera • Protista c. Plantae

  20. Identify the Kingdom I am a multicellular organism and I contain chorophyll. What kingdom do I belong to? • Fungi • Plantae c. Animalia

  21. Identify the Kingdom I am a unicellular organism that does not have a nucleus. What kingdom do I belong to? • Monera • Protista c. Fungi

  22. Identify the Kingdom I am a multicellular organism that can not make its own food. What kingdom do I belong to? • Monera • Protista c. Animalia

  23. Identify the Kingdom I am a multicellular organism that does not contain chlorophyll. My cell wall is different from a plant cell wall. What kingdom do I belong to? • Animalia • Plantae c. Fungi

  24. Classification of Living Organisms • Every organism can be classified at 7 different levels - kingdom, phylum, class, order, family, genus and species. • Each level has similar characteristics • Each successive group contains fewer organisms, but the organisms are more similar. • The species is the smallest group and is very narrow. • Important--Species are able to mate and produce fertile offspring

  25. Systematic Classification

  26. Binomial Nomenclature • Use last two names (genus and species) as in: • Ursus horribilis—the grizzly bear
