Study Notes
Introduction to Biology
- Biology is the scientific study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy.
- It encompasses a vast range of disciplines, including genetics, ecology, physiology, and molecular biology.
- Biology seeks to understand the fundamental principles that govern life processes.
- It's a multi-faceted field with ongoing research and advancements.
Key Concepts in Biology
- Cells: The fundamental units of life. All living organisms are composed of one or more cells.
- DNA: Deoxyribonucleic acid carries the genetic instructions for development, function, growth, and reproduction.
- Evolution: The process of change in the heritable characteristics of biological populations over successive generations.
- Homeostasis: The ability of an organism to maintain a stable internal environment despite changes in the external environment.
- Metabolism: All the chemical reactions that occur within an organism to sustain life.
- Reproduction: The process by which organisms give rise to offspring.
Branches of Biology
- Genetics: Studies heredity and variation in living organisms.
- Molecular Biology: Examines the structure and function of biological macromolecules.
- Cell Biology: Focuses on the structure and function of cells.
- Physiology: Explores the functions of organs and organ systems.
- Ecology: Studies the relationships between living organisms and their environment.
- Evolutionary Biology: Investigates the history of life on Earth, including the processes of speciation and extinction.
- Taxonomy: Classifies and names organisms based on their shared characteristics.
Biological Processes
- Photosynthesis: The process by which plants and other organisms use light energy to convert carbon dioxide and water into sugar.
- Cellular Respiration: The process by which organisms break down food molecules to release energy in the form of ATP.
- Protein Synthesis: The process by which cells use genetic information to build proteins.
- Growth and Development: The processes by which organisms increase in size and complexity.
- Reproduction: The processes by which organisms generate offspring.
Key Biological Principles
- The Cell Theory: The idea that all living things are composed of cells and that cells come from pre-existing cells.
- Natural Selection: The process by which organisms with advantageous traits are more likely to survive and reproduce.
- Genetic Inheritance: The passing of genetic traits from parents to offspring through genes.
- Homeostasis: The ability to regulate internal conditions.
Levels of Biological Organization
- Organism: A single living thing, such as a human, plant, or animal.
- Population: A group of organisms of the same species in a particular area.
- Community: All the populations of different species in a particular area.
- Ecosystem: A community of organisms and their physical environment.
- Biosphere: The sum of all ecosystems on Earth.
