Study Notes
Theories on the Origins of Life
- Theory of Special Creation: Life's formation attributed to supernatural forces; varies across religions, including the Christian and Islamic view of creation by God in six days.
- Theory of Eternity: Proposes that life forms have always existed and will continue to exist eternally, only changing in form over time.
- Theory of Panspermia: Introduced by Hermann Richter in 1865; suggests life originated from resistant spores (cosmozoa) that came to Earth, also known as the Cosmozoic Theory. Sir Fred Hoyle and Chandra Wickramasinghe support that interstellar dust and comets contained organic compounds.
- Theory of Catastrophism: Proposed by Baron Georges Cuvier; states life originates through creation followed by geographic catastrophes that lead to the evolution of different organisms.
- Theory of Abiogenesis: Biological life arises from inorganic matter via natural processes. The Oparin-Haldane hypothesis suggests life began in a "primordial soup." Disproven earlier ideas of spontaneous generation.
- Theory of Biogenesis: Life originates from pre-existing life. Louis Pasteur’s experiments challenged spontaneous generation, providing evidence for the continuity of life rather than the origin of the first organism.
Biological Organization
- Biological Organization: Characterizes organisms in a hierarchical structure, indicating levels of complexity within living systems.
The Development of Cell Theory
- Cell: Fundamental unit of life, all organisms consist of cells.
- Principles of Cell Theory:
- All organisms are made of one or more cells.
- The cell is the fundamental unit of life.
- Cells arise from pre-existing cells.
- Key Proponents:
- Robert Hooke (1665): Used a microscope on cork; described cells as "little boxes."
- Hans and Zacharias Janssen (1590s): Pioneered compound microscope development; achieved significant magnification.
- Anton van Leeuwenhoek (1674): First to observe live cells; named moving organisms "animalcules," discovered bacteria.
- Matthias Schleiden (1839): Confirmed plant tissues arise from cells; worked with Schwann on early cell theory principles.
- Theodor Schwann (1839): Established that animal structures consist of cells, contributed to cell theory formulation with Schleiden.
- Rudolf Virchow (1855): Introduced "omnis cellula e cellula," asserting all cells derive from pre-existing cells, noting disease arises from cell changes.
Introduction to Cell Structure and Function
- Plant Cell: Basic life unit in Plantae; characterized by unique structures not found in animal cells.
