    Study Notes

    Introduction and Terminology

    • Biology is the study of life and living organisms, including structure, function, growth, evolution, distribution, and taxonomy.
    • Studying biology is essential for medical students to understand the structure, function, and processes of the human body, as well as cells, organs, systems, genetics, and diseases.
    • Understanding biology is vital for diagnosis, treatment, medical research, and clinical decision-making.

    Branches of Biology

    • Botany: The study of plants, including structure, physiology, ecology, and evolution.
    • Zoology: The study of animals, covering behavior, physiology, anatomy, classification, and evolution.
    • Microbiology: The study of microorganisms (bacteria, viruses, fungi, protozoa), and their effects on health, agriculture, industry, and the environment.
    • Genetics: The study of heredity, variation, genes, chromosomes, inheritance patterns, and genetic disorders.
    • Ecology: Exploring interactions between organisms and their environment, including the relationships between living organisms, their habitats, ecosystems, and the biosphere.
    • Physiology: The study of the functions and processes of living organisms, and their parts, including cells, tissues, organs and organ systems.
    • Anatomy: Examining the structure of organisms, using dissection, imaging techniques, and comparative anatomy.
    • Biochemistry: The chemical processes and substances within living organisms, including the structure and function of biomolecules such as proteins, carbohydrates, lipids, and nucleic acids.
    • Biotechnology: Applying biological principles and techniques to develop products and technologies for medicine, agriculture, industry, and environmental conservation.
    • Cytology: The study of cells in terms of structure, function, and chemistry.
    • Histology: The microscopic study of plant and animal cells and tissues.
    • Immunology: The study of the immune system and its response to pathogens and foreign substances and their effects.
    • Embryology: The study of prenatal development, from gamete formation, fertilization, embryo and fetus development, and congenital disorders.
    • Teratology: A subset of embryology, focusing on congenital disorders occurring before birth

    Character of Living Organisms

    • Organization: Living organisms are made of cells, tissues, organs, organ systems, and the biosphere.
    • Metabolism: The sum of all chemical activities within cells/tissues.
    • Responsiveness: The ability to detect and respond to internal/external changes.
    • Growth: Increase in size and number of cells.
    • Development: All changes from fertilized egg to individual.
    • Reproduction: The ability of an organism to generate new individuals.
    • Homeostasis: Maintaining a stable internal state in response to outside change.

    Biological Organization

    • Chemical level: Atoms and molecules
    • Cellular level: Organelles, cells, tissues.
    • Organ level: Organs,
    • Organ system level: Organ systems,
    • Organism level: Individual organisms
    • Population level: Groups of similar individuals.
    • Community level: Interaction between multiple species
    • Ecosystem level: Interaction of living and non-living components.
    • Biosphere level: Combination of all Earth's ecosystems

    Diversity of Life

    • Scientists classify life into three domains: Archaea, Bacteria, and Eukarya.
    • Eukarya includes kingdom Protista, Fungi, Plantae, and Animalia.
    • The domains and kingdoms are further divided based on shared characteristics and evolutionary relationships.

    Scientific Method

    • Observation
    • Critical questions
    • Formulate a hypothesis
    • Make a prediction
    • Test the hypothesis with experiments
    • Analyze results
    • Develop a theory/principle
    • Interpretation and conclusion
    • Repeat experiments as necessary
