Study Notes
Introduction to Biology
- Biology is the study of life and living organisms
- It encompasses a wide range of topics, including the structure, function, growth, origin, evolution, distribution, and taxonomy of living things
- Biology helps to understand the diversity of life on Earth and the processes involved in maintaining life
- Biological fields cover different levels of organization, from molecules to ecosystems
Branches of Biology
- Cell Biology: Studies cells, the basic units of life, their structure, function, and interactions
- Genetics: Studies genes, heredity, and variation in living organisms. Includes inheritance patterns, gene expression, and genetic engineering
- Ecology: Studies how organisms interact with each other and their environment. Focuses on ecosystems, populations, communities, and biodiversity
- Evolutionary Biology: Studies how life on Earth has changed over millions of years, involving natural selection, adaptation, and speciation
- Microbiology: Focuses on microorganisms (bacteria, viruses, fungi, protists). Examines their structure, function, and applications
- Molecular Biology: Studies biological molecules (proteins, DNA, RNA) and their interactions
- Physiology: Studies the functions and processes within living organisms (like the human body) at cellular and organizational levels
- Botany: Studies plants, including their structure, function, classification, and ecology
- Zoology: Studies animals, including their structure, function, behaviour, and evolution
Key Biological Concepts
- The Cell Theory: All living things are made of cells, and all cells come from pre-existing cells
- Homeostasis: Maintaining a stable internal environment, despite external changes
- Evolution: Heritable changes in populations over generations, driven by natural selection (advantageous traits increase survival and reproduction)
- Energy Flow: Transfer and transformation of energy through living systems. Photosynthesis captures solar energy; respiration releases stored energy
- Heredity: Passing genetic information from parents to offspring, governed by Mendelian genetics and DNA
Biological Molecules
- Proteins: Complex molecules made of amino acids, vital for various life processes
- Carbohydrates: Essential for energy storage and structural support in organisms
- Lipids: Components of cell membranes and sources of energy storage
- Nucleic acids (DNA and RNA): Carry genetic information, direct protein synthesis, and regulate other cell processes
Biological Processes
- Metabolism: Sum of all chemical reactions in an organism, including catabolism (breaking down) and anabolism (building up)
- Photosynthesis: Plants and some other organisms convert light energy to chemical energy (glucose) from carbon dioxide and water
- Cellular Respiration: Breakdown of glucose to produce ATP (energy currency) and release water and carbon dioxide
- Reproduction: Creation of new organisms, can be asexual or sexual, essential for species continuity
- Growth and Development: Increase in size and complexity of an organism over time
Biodiversity
- Species: Group of organisms capable of interbreeding to produce fertile offspring
- Ecosystems: Community of organisms and their physical environment, interacting mutually
- Biodiversity: Variety of life on Earth (genes, species, ecosystems), crucial for the health of the planet
Scientific Methodology in Biology
- Observation: Gathering information about the natural world using senses
- Question Formulation: Developing specific questions based on observations
- Hypothesis Formation: Proposing testable explanations
- Experimentation: Designing and conducting controlled experiments to test the hypothesis
- Data Analysis: Evaluating and interpreting experimental results
- Conclusion: Summarizing findings based on analysis
