Study Notes
Introduction and Terminology
- Biology is the study of life and living organisms, encompassing their structure, function, growth, evolution, distribution, and taxonomy.
- Studying biology is essential for medical students.
- Biology forms the foundation for understanding the human body's structure, function, and processes.
- Knowledge of cells, organs, systems, genetics, and diseases is crucial for diagnosing and treating patients effectively.
- Understanding biology is key for scientific research and informed medical decision-making.
Branches of Biology
- Botany: Studies plants, including their structure, physiology, ecology, and evolution.
- Zoology: Focuses on animals, including behavior, physiology, anatomy, classification, and evolution.
- Microbiology: Examines microorganisms such as bacteria, viruses, fungi, and protozoa, considering their impact on health, agriculture, industry, and the environment.
- Genetics: Investigates inheritance, variation, and genetic disorders by studying genes, chromosomes, and inheritance patterns.
- Ecology: Investigates organism-environment interactions and ecosystem dynamics, including the relationships between living organisms and their habitats.
Branches of Biology (Continued)
- Physiology: Focuses on the functions and processes of living organisms, including cells, tissues, organs, and organ systems.
- Anatomy: Examines the structure of organisms, using dissection and imaging techniques for systematic study.
- Biochemistry: Studies chemical processes in living organisms, focusing on the composition and function of biomolecules like proteins, carbohydrates, lipids, and nucleic acids.
- Biotechnology: Applies biological principles and techniques to develop products and technologies in diverse fields such as medicine, agriculture, industry, and environmental conservation.
Branches of Biology (Continued)
- Cytology: The study of cells, focusing on their structure, function, and chemistry.
- Histology: The study of tissues, examining the microscopic anatomy of plant and animal tissues.
- Immunology: Investigates the immune system's response to pathogens and foreign substances.
- Embryology: Studies prenatal development in gametes, fertilization, and embryonic development and congenital disorders.
Characters of Living Organisms
- Organisms are composed of cells (unicellular or multicellular).
- Growth involves an increase in size and number of cells.
- Development encompasses changes from fertilized egg to an individual.
- Reproduction is the ability to create new individuals of the same kind (asexual or sexual).
- Organisms exhibit movement in various ways, from microorganism to animal.
- Metabolism refers to all the chemical processes in an organism.
Characters of Living Organisms (Continued)
- Homeostasis is the maintenance of a stable internal environment.
- Organisms adapt to their surroundings.
- Organisms react to stimuli in their environment and internally.
Biological Organization
- Chemical level: Includes atoms and molecules.
- Cellular level: Consists of organelles, cells, and tissues.
- Organ level: Includes various types of tissues working together.
- Organ system level: Composed of organs that work together.
- Organism level: Represents an individual living entity.
- Population level: Includes all individuals of a similar species in a defined region.
- Community level: Includes all populations of the different species in a specific area.
- Ecosystem level: Includes community and non-living components interacting.
- Biosphere: Consists of all ecosystems on Earth.
Diversity of Life
- Scientists classify the diverse life forms into various kingdoms and finer groups (including bacteria, archaea, and eukarya).
- Modern classifications often consider DNA sequencing and other relevant characteristics.
Diversity of Life (Continued)
- Archea: Prokaryotic, single-celled, microscopic, reproduce by binary fission.
- Bacteria: Prokaryotic, single-celled, microscopic, reproduce by binary fission.
- Protists: Mostly unicellular eukaryotic organisms, either autotrophic or heterotrophic.
- Fungi: Eukaryotic, typically multicellular, heterotrophic, and saprotrophic.
- Plants: Multicellular eukaryotic autotrophs with cell walls consisting mostly of cellulose.
- Animals: Heterotrophic, multicellular eukaryotes.
Scientific Method
- Observation of phenomena often generates critical questions.
- A hypothesis is formulated to provide a possible answer.
- Specific predictions are made from the hypothesis
- Experiments are designed to test the predicted outcome.
- Results will provide support for, or refutation of, the hypothesis.
- Results are interpreted and explained as a theory.
