Study Notes
Introduction and Terminology
- Biology is a natural science studying life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy.
- Medical students need to study biology to understand how the human body's structure, function, and processes work.
- Knowledge of cells, organs, systems, genetics, and diseases is crucial in medical college for diagnosing and treating patients.
- Understanding biology is key to medical research and decision-making; crucial for clinical practice.
Branches of Biology
- Botany: Study of plants, including their structure, physiology, ecology, and evolution.
- Zoology: Study of animals, covering behavior, physiology, anatomy, classification, and evolution.
- Microbiology: Study of microorganisms (bacteria, viruses, fungi, and protozoa) and their impact on health, agriculture, industry, and the environment; includes their effects on health, industry, and agriculture.
- Genetics: Study of heredity and variation, including genes, chromosomes, genetic traits, inheritance patterns, and genetic disorders.
- Ecology: Study of interactions between organisms and their environment, covering their habitats, ecosystems, and the biosphere; emphasis on the relationship between organisms and environment.
Branches of Biology (continued)
- Physiology: Examines the functions and processes of living organisms (cells, tissues, organs, and organ systems).
- Anatomy: Investigates organism structure (using dissection, imaging techniques, and comparative anatomy).
- Biochemistry: Study of chemical processes and substances in living organisms (proteins, carbohydrates, lipids, and nucleic acids).
- Biotechnology: Application of biological principles and techniques to develop products and technologies, including in medicine, agriculture, industry, and environment conservation.
Branches of Biology (continued)
- Cytology: Study of cells; examining cell structure and function.
- Histology: Study of microscopic anatomy of tissues and cells.
- Immunology: Study of the immune system; understanding the immune responses against foreign substances and pathogens.
- Embryology: Studies prenatal development of gametes, fertilization, development of embryos, and fetuses (including congenital disorders before birth).
Characters of Living Organisms
- Organisms are composed of cells: Basic structural and functional units.
- Unicellular organisms: Consists of one cell (e.g., Protozoa).
- Multicellular organisms: Consists of many cells (e.g., humans).
- Growth: Increase in size and number of cells.
- Development: Process involving changes from fertilized egg to a mature individual.
Characters of Living Organisms (continued)
- Reproduction: Ability to reproduce.
- Asexual: Reproduction without fusion of egg and sperm.
- Sexual: Reproduction involving fusion of egg and sperm.
- Movement: Internal or external movement.
- Metabolism: Sum of chemical activities in cells and tissues.
Characters of Living Organisms (continued)
- Homeostasis: Balanced internal state of physical, chemical, and social conditions maintained.
- Homeostatic range: Body temperature and fluid balance maintained within certain limits.
- Other variables regulated: sodium, potassium, calcium, and blood sugar levels; influenced by the internal environment as well as an external environment.
- These are controlled by homeostatic mechanisms; critical for survival.
Characters of Living Organisms (continued)
- Response to Stimuli: Organisms changing their internal or external environment response to changes in external environment; a key characteristic of life, including internal responses.
- Includes reflex actions, movement towards stimuli, adaptation to new circumstances.
- Examples: changes in heart rate or hormone secretion; organisms responding to environmental cues.
- Adaptation: Ability to survive in specific environment; influenced by the ability of the organism to adapt to its environment and its responses to environmental cues.
Biological Organization
-
Chemical Level: Atom and Molecule
-
Atoms: Smallest building blocks of matter; basic units.
-
Molecules: Atoms chemically bonded; combination of atoms.
-
Cellular Level: Organelles, cells, tissues
-
Organelles: Specialized subunits within the cell.
-
Cells: Basic structural and functional units of life.
-
Tissues: Group of similar cells working together.
Biological Organization (Continued)
- Organ level: Organ systems, organism
- Organs: Groups of tissues performing a specific function.
- Organ Systems: Groups of organs functioning together.
- Organism: Individual carrying out life processes.
Biological Organization (Continued)
- Ecological Level: Populations, communities, ecosystems, biosphere
- Populations: Individuals of the same species in a specific area.
- Communities: Populations of different species in a particular area interacting; including how species interact in specific environment.
- Ecosystems: Community and its non-living environment interacting; important to consider the natural interactions.
- Biosphere: Combination of all Earth's ecosystems globally.
Diversity of Life
- Scientists classify life into kingdoms, with further classifications based on structure, function, and DNA analysis; organisms classified based on cellular organization, evolutionary relationships, etc.
- Three domains of life: Bacteria, Archaea, and Eukarya.
Diverse of Life (Continued)
- Kingdom: Eukarya
- Kingdom Protista: Most unicellular or some multicellular, autotrophic or heterotrophic. (e.g., protozoa, eukaryotic algae, and molds).
- Kingdom Fungi: Eukaryotic (multicellular or unicellular), heterotrophic that usually decomposes/break down substances; crucial role in decomposition and nutrient cycling in an ecosystem.
- Kingdom Plantae: Multicellular eukaryotic and autotrophic, use photosynthesis to produce energy.
- Kingdom Animalia: Multicellular eukaryotic (no cell wall), heterotrophic, using other organisms for nutrients.
Scientific Method
- Observations: Initial observations that lead to research.
- Developing questions: Involves critical thinking and the posing of relevant questions.
- Creating hypothesis: A prediction based on observations and questions.
- Creating experiments and predictions: Involve testing the hypothesis to confirm the prediction.
- Gathering results: Results from experiments to assess if the initial hypothesis was fulfilled.
- Interpretation and Conclusions: Evaluate the results of experiments to give an interpretation based on results, draw conclusion, and possibly create a theory.
- Further experiments and new hypothesis: A loop starting with observation and critical questions; a crucial element in scientific process and research.
