Study Notes
Unifying Themes in Biology
- Biological systems encompass a network of interconnected entities, ranging from atoms to the biosphere.
- Higher organization is structured in levels: atom, molecule, cell, tissue, organ, organ system, organism, population, community, ecosystem, and biosphere.
- Structure and function are intrinsically linked: form dictates purpose at both cellular and organismal levels.
- Reproduction occurs via genetic combinations from parents, directing development of traits like eye color and facial features through DNA.
- Life necessitates energy transfer and transformation, imperative for sustaining biological functions.
- Organisms continuously interact with their environment, which includes other organisms and physical factors, emphasizing the interconnectedness within ecosystems.
Theories of Life
- Creation Theory posits divine forces initiated life, supported by religious texts like the Book of Genesis.
- Abiogenesis describes life emerging from non-living matter, a spontaneous process historically supported by figures like Aristotle but later challenged by experiments from Redi, Spallanzani, and Pasteur.
- Biogenesis asserts all living organisms arise from pre-existing life, embodying the principle of "Life from Life."
Cell Theory
- All organisms consist of one or more cells; a cell is the fundamental unit of life.
- This theory states cells arise from pre-existing cells, contradicting spontaneous generation notions.
Characteristics of Living Things
- Living entities metabolize substances, facilitating functions like nutrient transport, waste removal, and energy transformation.
- Growth and development occur through cell division and enlargement; non-living entities like crystals can also exhibit growth.
- Organisms react to stimuli (light, temperature, sound, etc.), which prompt physical or behavioral changes.
- Symbiosis describes interactions between different organisms sharing habitats, crucial in understanding ecological dynamics.
- Reproduction is vital for species continuation, with all organisms possessing genetic information to ensure generational succession.
Science, Technology, and Society
- The intersection of science and technology reflects an interdependent relationship, where scientific discoveries lead to technological inventions.
- Modern biology significantly influences daily human life; a notable example includes the 2013 prototype of a bionic eye developed in Australia, enabling image perception through brain microchips.
