Overview of Biology and Its Branches

Definition: Biology is the scientific study of life and living organisms, encompassing various aspects such as structure, function, growth, evolution, and distribution.

Botany: Study of plants, including their physiology, structure, genetics, ecology, and classification.
Zoology: Study of animals, covering their behavior, physiology, classification, and distribution.
Microbiology: Study of microorganisms, including bacteria, viruses, fungi, and protozoa.
Ecology: Study of interactions between organisms and their environment.
Genetics: Study of heredity and variation in living organisms.
Cell Biology: Study of cell structure, function, and processes.
Evolutionary Biology: Study of the origins and changes in the diversity of life over time.

Cell Theory: All living organisms are composed of cells, and all cells arise from pre-existing cells.
Evolution: The process through which species change over time due to natural selection and genetic drift.
Homeostasis: The ability of an organism to maintain stable internal conditions despite external changes.
Metabolism: The set of life-sustaining chemical reactions in organisms, including anabolism and catabolism.
DNA and RNA: Nucleic acids responsible for the storage and transmission of genetic information.

Photosynthesis: Process by which green plants and some other organisms convert light energy into chemical energy in the form of glucose.
Cell Respiration: The metabolic processes that convert glucose into ATP (energy) using oxygen.
Protein Synthesis: Process of creating proteins from amino acids based on the information in mRNA.

Biosphere: Global sum of all ecosystems.
Ecosystem: Community of living organisms and their physical environment.
Community: Different species living together in a particular area.
Population: Group of individuals of the same species living in a specific area.
Organism: Individual living entity.
Organ System: Group of organs working together for a specific function.
Organ: Structure composed of different types of tissues.
Tissue: Group of cells with a common structure and function.
Cell: Basic unit of life.
Organelle: Specialized structure within a cell.

Observation: Noting and recording phenomena to gather data.
Experimentation: Conducting controlled tests to explore hypotheses.
Modeling: Using computational or physical models to simulate biological processes.
Field Studies: Observing organisms in their natural habitat to gather ecological data.

Understanding Life: Provides insights into the complexity and interconnections of life forms.
Medical Advancements: Contributes to improvements in healthcare, pharmaceuticals, and biotechnology.
Environmental Conservation: Informs strategies for biodiversity conservation and ecosystem management.

Biology is the study of life and living organisms.
It covers aspects like structure, function, growth, evolution, and distribution.

Botany studies plants, including their structure, physiology, genetics, ecology, and classification.
Zoology focuses on animals, covering their behavior, physiology, classification, and distribution.
Microbiology studies microorganisms, such as bacteria, viruses, fungi, and protozoa.
Ecology investigates the interactions between organisms and their environment.
Genetics studies heredity and the variation in living organisms.
Cell Biology focuses on the structure, function, and processes within cells.
Evolutionary Biology studies the origins and changes in the diversity of life over time.

Cell Theory states that all living organisms are composed of cells, and all cells arise from pre-existing cells.
Evolution is the process of change in species over time, driven by natural selection and genetic drift.
Homeostasis is the ability of an organism to maintain a stable internal environment despite external changes.
Metabolism involves the set of life-sustaining chemical reactions in organisms, encompassing anabolism (building up) and catabolism (breaking down).
DNA and RNA are nucleic acids responsible for storing and transmitting genetic information.

Photosynthesis is the process by which green plants and some organisms convert light energy into chemical energy (glucose).
Cell Respiration uses oxygen to convert glucose into ATP (energy) for cellular processes.
Protein Synthesis involves creating proteins from amino acids based on the information in mRNA.
