Study Notes
Cell Biology Focus
- The main focus of cell biology is the study of cells, the fundamental units of life.
- Cell biology investigates the structure, function, and behavior of cells, as well as their interactions with each other and their environment.
Genetics
- Genetics is the study of genes, heredity, and the variations in living organisms.
- It explores how traits are passed from one generation to the next.
Ecology
- Ecology examines the interactions between organisms and their environment.
- It focuses on the relationships between living organisms and their physical surroundings, including factors like population dynamics, biodiversity, and ecosystem function.
Evolutionary Biology
- Evolutionary biology investigates the processes that have led to the diversity of life on Earth.
- It explores how species have changed over time through mechanisms like natural selection, genetic drift, and gene flow.
Biology Fields and Their Focus
- Botany: The study of plants.
- Zoology: The study of animals.
- Microbiology: The study of microorganisms, including bacteria, viruses, fungi, and protozoa.
- Ecology: The study of interactions between organisms and their environment.
- Genetics: The study of genes, heredity, and variation in organisms.
Genetics Processes
- Genetics studies various processes, including:
- DNA replication: The process of copying DNA.
- Transcription: The process of creating RNA from DNA.
- Translation: The process of creating proteins from RNA.
- Gene expression: The process of turning genes "on" or "off".
- However, genetics does not directly focus on cell differentiation.
Microbiology
- Microbiology is a key area of study within biology that focuses on microorganisms, which are tiny, single-celled or multicellular organisms.
- This includes bacteria, viruses, fungi, and protozoa.
Basic Units of Life
- According to cell biology, the basic units of life are called cells.
- Cells are the smallest structural and functional units of all living organisms.
