    Study Notes

    Development of Cell Theory

    • Matthias Schleiden (1838): All plant parts are composed of cells.
    • Theodor Schwann (1839): All animal tissues are made up of cells.
    • Rudolf Virchow (1858): Concluded that cells arise only from preexisting cells.
    • Cell Theory:
      • All living things consist of one or more cells.
      • Cells are the basic units of structure and function in organisms.
      • Cells originate only from existing cells.

    Historical Figures in Biology

    • Aristotle: Known as the "Father of Biology" and "Father of Zoology," he used systematic observation to study living organisms, contributing to taxonomy and animal behavior.
    • Claudius Galen: Greek physician who studied human anatomy via dissections; errors in his findings were unchallenged for 1,300 years.
    • Andreas Vesalius: The "Father of Modern Anatomy," he conducted detailed human anatomy studies and pioneered comparative anatomy methods.
    • William Harvey: Demonstrated that the heart pumps blood, establishing the principles of circulation and integrating structure and function in anatomy.
    • Anton van Leeuwenhoek: "Father of Microbiology" and "Father of Cell Biology," made pioneering discoveries in microscopic life with the advent of the microscope.
    • Carolus Linnaeus: "Father of Taxonomy," developed the Binomial Nomenclature system for classifying and naming species, still in use today.
    • Gregor Johann Mendel: "Father of Genetics," formulated the principles of heredity through studies on pea plant traits.
    • Charles Darwin: His work in "Origin of Species" introduced the Theory of Evolution by Natural Selection, shaping modern biological thought.

    Major Discoveries in Molecular Biology

    • 1953: James Watson, Francis Crick, Maurice Wilkins, and Rosalind Franklin identified the double helix structure of DNA, crucial for understanding heredity.

    Types of Science

    • Natural Sciences: Includes fields like biology, chemistry, and physics, often referred to as "hard science" for their reliance on quantitative data.
    • Basic Science: Focuses on knowledge expansion without immediate application, prioritizing pure understanding of phenomena.
    • Applied Science: Uses scientific knowledge to address real-world problems, leading to practical applications.

    Properties of Life

    • All living organisms share key characteristics: Order, Sensitivity, Reproduction, Adaptation, Growth and Development, Regulation, Homeostasis, and Energy Processing.

    Characteristics of Life

    • Order: Highly organized structures made up of one or more cells; multicellular organisms benefit from specialized cell functions.
    • Sensitivity: Organisms respond to environmental stimuli through mechanisms like chemotaxis (chemical response) and phototaxis (light response).
    • Reproduction: Offspring inherit genetic material from parents, ensuring species continuity.
    • Adaptation: Organisms fit to their environment via adaptations shaped by natural selection, which evolve over generations.
    • Growth and Development: Organisms grow according to genetic instructions, ensuring young exhibit parental characteristics.
    • Regulation: Organisms maintain complex internal mechanisms to coordinate functions and respond to external stresses.
    • Homeostasis: Ability to maintain a stable internal environment despite external changes, such as temperature regulation in mammals.
    • Energy Processing: Organisms utilize energy, often derived from food sources, for metabolic activities.
