    Study Notes

    Biology Overview

    • Definition: The scientific study of life and living organisms, encompassing their structure, function, growth, evolution, distribution, and taxonomy.

    Branches of Biology

    1. Molecular Biology: Studies biological processes at the molecular level, including interactions between DNA, RNA, proteins, and their biosynthesis.
    2. Cell Biology: Focuses on the structure and function of cells, the basic units of life.
    3. Genetics: Examines heredity, genetic variation, and the role of genes in organisms.
    4. Evolutionary Biology: Studies the origins and changes in the diversity of life over time.
    5. Ecology: Investigates interactions between organisms and their environments, including ecosystems and biomes.
    6. Physiology: Explores the functions and mechanisms in living organisms.

    Fundamental Concepts

    • Cell Theory: All living organisms are composed of cells; the cell is the basic unit of life; all cells arise from pre-existing cells.
    • Evolution: The process by which populations of organisms change over generations through natural selection, mutation, gene flow, and genetic drift.
    • Homeostasis: The ability of an organism to maintain stable internal conditions despite external changes.

    Levels of Biological Organization

    1. Molecules: The building blocks of life (e.g., proteins, nucleic acids).
    2. Cells: Basic unit of life; can be prokaryotic (no nucleus) or eukaryotic (nucleus present).
    3. Tissues: Groups of similar cells performing a specific function.
    4. Organs: Structures composed of different tissues working together.
    5. Organ Systems: Groups of organs that perform complex functions (e.g., digestive system).
    6. Organisms: Individual living entities.
    7. Populations: Groups of individuals of the same species living in a specific area.
    8. Communities: Different populations living together in a defined area.
    9. Ecosystems: Communities plus their physical environment.
    10. Biosphere: The global sum of all ecosystems, where life exists.

    Ecological Concepts

    • Niche: The role of an organism in its environment.
    • Food Chain/Food Web: Hierarchical structure representing energy flow through ecosystems.
    • Biomagnification: Increase in concentration of toxins in organisms at each trophic level.
    • Biodiversity: Variety of life in the world or a specific habitat.

    Basic Processes of Life

    • Metabolism: Sum of all chemical reactions in an organism, including anabolism (building up) and catabolism (breaking down).
    • Reproduction: The biological process by which new individual organisms are produced; can be sexual or asexual.
    • Growth and Development: Includes the processes by which organisms develop from a single cell to complex systems.

    Important Figures in Biology

    • Charles Darwin: Formulated the theory of evolution by natural selection.
    • Gregor Mendel: Known as the father of modern genetics; studied inheritance through pea plants.
    • Louis Pasteur: Pioneered work in microbiology and pasteurization.

    Scientific Method

    1. Observation: Gathering information about a phenomenon.
    2. Hypothesis: Formulating a testable explanation.
    3. Experimentation: Conducting experiments to test the hypothesis.
    4. Data Analysis: Evaluating the results of experiments.
    5. Conclusion: Drawing conclusions based on the data; may lead to further hypotheses.
