Biology Branches

Branches of Biology

• Botany: study of plants, including their structure, growth, evolution, classification, and distribution
• Zoology: study of animals, including their structure, behavior, evolution, classification, and distribution
• Microbiology: study of microorganisms, such as bacteria, viruses, and other microbes
• 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
• Biophysics: study of the physical principles underlying biological processes
• Molecular Biology: study of the structure and function of biological molecules, such as DNA and proteins

Cell Biology

• A cell is the basic unit of life, consisting of a nucleus, cytoplasm, and cell membrane
• Cellular organelles: specialized structures within cells that perform specific functions, such as mitochondria (energy production) and ribosomes (protein synthesis)
• Cell division: process by which cells reproduce, including mitosis (somatic cells) and meiosis (gametes)

Evolution

• Theory of evolution: all species share a common ancestor and have evolved over time through natural selection and genetic variation
• Natural selection: process by which individuals with favorable traits are more likely to survive and reproduce, leading to adaptation and speciation
• Speciation: process by which a new species emerges from an existing one

Biological Molecules

• Carbohydrates: provide energy for cells, examples include glucose and cellulose
• Proteins: perform a wide range of functions, including structural, enzymatic, and transport roles
• Lipids: provide energy storage and play a role in cellular structure, examples include fats and oils
• Nucleic acids: contain genetic information, examples include DNA and RNA

Ecosystems

• Ecosystem: community of living organisms and their environment, interacting through energy flow and nutrient cycling
• Food chain: sequence of organisms that eat other organisms, with energy flowing from one level to the next
• Food web: network of interconnected food chains, showing the complex relationships between organisms in an ecosystem

• A cell is the basic unit of life, consisting of a nucleus, cytoplasm, and cell membrane.
• Cellular organelles are specialized structures within cells that perform specific functions, such as mitochondria for energy production and ribosomes for protein synthesis.
• Cell division is the process by which cells reproduce, including mitosis for somatic cells and meiosis for gametes.
