Study Notes
Overview of Biology
- Biology is the scientific study of life and living organisms
- It involves the study of structure, function, growth, evolution, and taxonomy of all living organisms
- Biology explores the diversity of life on Earth, from the simplest bacteria to complex ecosystems
Branches of Biology
- Botany: study of plants and plant-like organisms
- Zoology: study of animals and animal-like organisms
- Microbiology: study of microorganisms such as bacteria and viruses
- Ecology: study of interactions between organisms and their environment
- Genetics: study of heredity, genes, and genetic variation
- Biochemistry: study of chemical processes and molecules that occur within living organisms
Cell Biology
- Cell: basic structural and functional unit of life
- Cell membrane: thin layer of lipid and protein molecules that surrounds the cell
- Cytoplasm: jelly-like substance inside the cell membrane where metabolic processes occur
- Nucleus: control center of the cell where DNA is stored
- Mitosis: process of cell division resulting in two identical daughter cells
Evolution and Classification
- Theory of Evolution: explains how species change over time through natural selection and genetic drift
- Species: group of organisms that can interbreed and produce fertile offspring
- Taxonomy: classification of organisms based on their evolutionary relationships
- Domain, Kingdom, Phylum, Class, Order, Family, Genus, Species: hierarchical classification system
Biological Molecules
- Carbohydrates: provide energy for the cell (e.g., glucose, starch)
- Proteins: perform various cellular functions (e.g., enzymes, hormones)
- Lipids: store energy and provide structure (e.g., fats, oils)
- Nucleic Acids: store genetic information (e.g., DNA, RNA)
Biological Processes
- Photosynthesis: process by which plants convert light energy into chemical energy
- Respiration: process by which cells generate energy from glucose
- Metabolism: set of chemical reactions that occur within the cell
- Homeostasis: ability of an organism to maintain a stable internal environment despite changes in the external environment
