Study Notes
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
- Biochemistry: study of chemical processes in living organisms
- Molecular Biology: study of molecular structures and processes in living organisms
- Genetics: study of heredity and variation in organisms
Cell Biology
- Cell structure: plasma membrane, cytoplasm, nucleus, mitochondria, etc.
- Cell functions: metabolism, growth, reproduction, response to stimuli
- Cell division: mitosis (somatic cells), meiosis (gametes)
- Cellular transport: passive (diffusion, osmosis), active (carrier proteins)
Genetics
- Mendel's laws: segregation, independent assortment, dominance
- DNA structure: double helix, nucleotides, base pairing
- Gene expression: transcription, translation, protein synthesis
- Inheritance patterns: autosomal, sex-linked, polygenic, epistatic
Evolution
- Mechanisms: mutation, genetic drift, gene flow, natural selection
- Evidence: fossil record, comparative anatomy, molecular biology
- Types of evolution: microevolution, macroevolution, speciation
- Evolutionary relationships: phylogenetic trees, cladistics
Ecosystems
- Energy flow: producers, consumers, decomposers, trophic levels
- Nutrient cycling: carbon, nitrogen, oxygen, water
- Ecosystem services: provisioning, regulating, cultural, supporting
- Biomes: terrestrial (forest, grassland, desert), freshwater, marine
Biological Molecules
- Carbohydrates: sugars, starches, cellulose, glycogen
- Proteins: structure, function, amino acids, enzymes
- Lipids: fats, oils, cholesterol, phospholipids
- Nucleic acids: DNA, RNA, nucleotides, base pairing
