Study Notes
Branches of Biology
- Botany: study of plants
- Zoology: study of animals
- Microbiology: study of microorganisms
- Ecology: study of interactions between organisms and their environment
- Biochemistry: study of chemical processes in living organisms
- Molecular Biology: study of structure and function of biological molecules
- Genetics: study of heredity and variation
- Evolutionary Biology: study of evolution and diversity of life
Cell Biology
- Cellular structure: cell membrane, cytoplasm, nucleus, mitochondria, ribosomes
- Cell functions: metabolism, growth, reproduction, response to stimuli
- Cell division: mitosis, meiosis
- Cellular transport: passive transport (diffusion, osmosis), active transport
Genetics
- Mendel's Laws: segregation, independent assortment, dominance
- Inheritance patterns: autosomal, sex-linked, polygenic
- DNA structure: double helix, nucleotides (A, C, G, T)
- Gene expression: transcription, translation
Evolution
- Mechanisms: mutation, genetic drift, gene flow, natural selection
- Types of evolution: microevolution, macroevolution
- Fossil record: evidence for evolution
- Comparative anatomy and embryology: evidence for evolution
Ecosystems
- Biotic factors: living organisms (producers, consumers, decomposers)
- Abiotic factors: non-living components (light, temperature, water, soil)
- Energy flow: trophic levels, food chains, food webs
- Nutrient cycles: carbon, nitrogen, oxygen, water
Biological Molecules
- Carbohydrates: sugars, starches, cellulose
- Proteins: amino acids, structure, function
- Lipids: fats, oils, steroids
- Nucleic acids: DNA, RNA, structure, function
