Study Notes
Definition and Scope
- Biology is the scientific study of life and living organisms
- It encompasses the structure, function, growth, evolution, distribution, and taxonomy of all living things
Branches of Biology
- Botany: study of plants
- Zoology: study of animals
- Microbiology: study of microorganisms (bacteria, viruses, etc.)
- Ecology: study of interactions between organisms and their environment
- Genetics: study of heredity, genes, and genetic variation
- Biochemistry: study of chemical processes and substances in living organisms
- Molecular Biology: study of biological processes at the molecular level
- Evolutionary Biology: study of the evolution of living organisms
Biological Molecules
- Carbohydrates: provide energy and structure (e.g., sugars, starches)
- Proteins: perform various functions (e.g., enzymes, hormones, structural proteins)
- Nucleic Acids: store genetic information (e.g., DNA, RNA)
- Lipids: provide energy and structure (e.g., fats, oils)
Cellular Structure and Function
- Cell membrane: regulates what enters and leaves the cell
- Cytoplasm: site of metabolic processes
- Nucleus: contains genetic material
- Mitochondria: site of cellular respiration
- Ribosomes: site of protein synthesis
Biological Processes
- Photosynthesis: process by which plants convert light energy into chemical energy
- Respiration: process by which cells generate energy from glucose
- Cell division: process by which cells reproduce
- Gene expression: process by which genetic information is used to create proteins
Ecosystems and Ecology
- Ecosystem: community of living and non-living components interacting with each other
- Biodiversity: variety of species in an ecosystem
- Food chains: series of organisms that eat other organisms
- Food webs: complex networks of food chains
Evolution and Natural Selection
- Evolution: change in species over time
- Natural selection: process by which species adapt to their environment
- Speciation: process by which new species emerge
- Adaptation: trait that helps an organism survive and reproduce in its environment
