Study Notes
Definition and Scope
- Biology is the scientific study of life and living organisms, including their structure, function, growth, evolution, distribution, and taxonomy.
- It explores the diversity of life forms, from molecules to ecosystems.
Branches of Biology
- Botany: study of plants, including their structure, growth, evolution, classification, and interactions with the environment.
- Zoology: study of animals, including their structure, behavior, evolution, classification, and interactions with the environment.
- Microbiology: study of microorganisms, including bacteria, viruses, and other microorganisms.
- Ecology: study of the relationships between organisms and their environment.
Cell Biology
- Cell: the basic structural and functional unit of life, consisting of cell membrane, cytoplasm, and genetic material (DNA or RNA).
- Cellular organelles: specialized structures within cells, such as mitochondria, chloroplasts, and ribosomes, that perform specific functions.
- Cell division: process by which cells reproduce, including mitosis and meiosis.
Genetics
- Genes: units of heredity that carry information from one generation to the next.
- Genotype: genetic makeup of an individual, including all its genes.
- Phenotype: physical and behavioral characteristics of an individual, resulting from the interaction of its genotype and environment.
- Mendelian inheritance: principles of heredity, including segregation, independent assortment, and dominance.
Evolution
- Theory of evolution: process by which species change over time through natural selection, genetic drift, mutation, and gene flow.
- Natural selection: mechanism by which individuals with favorable traits are more likely to survive and reproduce, passing those traits to their offspring.
- Species: group of interbreeding organisms that can produce fertile offspring.
Ecosystems and Ecology
- Ecosystem: community of organisms and their physical environment, interacting through nutrient cycles, energy flow, and species interactions.
- Food chain: sequence of organisms that eat other organisms, with energy flowing from one level to the next.
- Energy pyramid: representation of energy flow through an ecosystem, with producers at the base and top predators at the apex.
