Study Notes
Introduction and Terminology
- Biology is a natural science, focusing on the study of life and living organisms. This includes their structure, function, growth, evolution, distribution, and taxonomy.
- Studying biology is essential for medical students to understand the structure, function, and processes of the human body. This includes knowledge of cells, organs, systems, genetics, and diseases.
- Knowledge of biology is crucial for diagnosing and treating patients, conducting research, and making informed clinical decisions.
Branches of Biology
- Botany: The study of plants, including their structure, physiology, ecology, and evolution.
- Zoology: The study of animals, encompassing behavior, physiology, anatomy, classification, and evolution.
- Microbiology: Focuses on microorganisms, including bacteria, viruses, fungi, and protozoa, and their impact on health, agriculture, and the environment.
- Genetics: The study of heredity and variation; including genes, chromosomes, genetic traits, inheritance patterns, and disorders.
- Ecology: The study of relationships between organisms and their environment, focusing on interactions between living things and their habitats and ecosystems.
- Physiology: The study of the functions and processes of living organisms and their parts, from cells to organ systems.
- Anatomy: Examines the structure of organisms, studying tissues, organs, and organ systems. Often including dissection and imaging techniques.
- Biochemistry: Investigates chemical processes and substances within living organisms, such as proteins, carbohydrates, lipids, and nucleic acids.
- Biotechnology: The application of biological principles and techniques for developing products and technologies (medical, agricultural, industrial, and conservation).
- Cytology: The study of cells, focusing on structure, function, and chemistry.
- Histology: The study of microscopic anatomy of tissues and cells from plants and animals.
- Immunology: The study of the immune system and its response to pathogens, foreign substances, and diseases.
- Embryology: The study of prenatal development, including the early stages of life, and includes congenital disorders that arise before birth.
Characters of Living Organisms
- Reproduction: The ability of an organism to create a new generation of the same kind through sexual or asexual processes.
- Movement: The ability to change location.
- Metabolism: Sum of all chemical processes inside the organism's cells and tissues.
- Homeostasis: A balanced internal state, maintaining conditions such as body temperature, water balance, and chemical regulation.
- Response to Stimuli: The capacity to detect and respond to changes in the environment (internal and external).
- Adaptation: A form of survival – the ability to adjust and thrive in a particular environment.
Biological Organization
- Chemical Level: Atoms are the fundamental building blocks of matter, forming molecules (groups of atoms held together chemically).
- Cellular Level: Organelles are specialized units within cells that perform specific functions. Cells are the basic structural and functional units in organisms. Tissues are composed of similar or dissimilar cells performing a similar purpose.
- Organ Level: Organs are formed of different tissue types working together.
- Organ System Level: Organ systems are teams of organs working towards a larger function.
- Organism Level: An individual living entity.
- Population Level: All organisms of the same species in a particular area.
- Community Level: Different species interacting in a particular area.
- Ecosystem Level: Community interacting with its surroundings (living and non-living).
- Biosphere Level: All combined ecosystems.
Diversity of Life
- Scientists classify living things into groups based on various characteristics.
- Domains of life: Bacteria, Archaea, and Eukarya.
- Kingdoms within Eukarya: Protista, Fungi, Plantae, and Animalia.
- The study of diversity depends on DNA sequencing.
Scientific Method
- A framework for scientific research, from observation to hypothesis testing to the development of theories.
