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 is a vast and diverse field that explores all aspects of life, 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, such as bacteria, viruses, and other microorganisms.
- Ecology: study of the interactions between organisms and their environment.
- Genetics: study of heredity, genes, and genetic variation.
- Biochemistry: study of the chemical processes that occur within living organisms.
- Molecular Biology: study of the structure, function, and interactions of biological molecules, such as DNA, proteins, and other biomolecules.
Biological Molecules
- Carbohydrates: provide energy and structure to cells.
- Proteins: perform a wide range of functions, including enzymes, hormones, and structural components.
- Lipids: provide energy and structure to cells, and are a key component of cell membranes.
- Nucleic Acids: store and transmit genetic information, including DNA and RNA.
Cell Biology
- Cell Structure: cells are the basic units of life, consisting of a cell membrane, cytoplasm, and genetic material.
- Cellular Processes: cells perform a range of functions, including metabolism, photosynthesis, and cell division.
- Cell Signaling: cells communicate with each other through signaling pathways.
Evolution and Diversity
- Evolution: the process by which species change over time through natural selection, genetic drift, and other mechanisms.
- Species: a group of organisms that can interbreed and produce fertile offspring.
- Phylogeny: the study of the evolutionary relationships between organisms.
- Biodiversity: the variety of different species, ecosystems, and genes within an ecosystem or on Earth as a whole.
Ecosystems and Ecology
- Ecosystems: communities of living and non-living components that interact with each other.
- Energy Flow: energy flows from producers to consumers through food chains and webs.
- Nutrient Cycles: nutrients are cycled through ecosystems through processes such as decomposition and nutrient uptake.
- Ecological Interactions: species interact with each other and their environment through competition, predation, and symbiosis.
