Study Notes
Genetics
- Deals with the transmission of traits/characteristics from parents to offspring
- Involves mechanisms of heredity and variation at the molecular and cellular levels
Physiology
- Deals with functions or activities of the parts of organisms at the molecular, cellular, and gross-anatomical levels
- Subdivisions:
- Microbial Physiology: deals with genetic and genetic mutations of microorganisms, especially viruses and bacteria
- Plant Physiology: deals with functions or activities of plant body parts
- Animal Physiology: deals with functions or activities of animal body parts
Developmental Biology
- Deals with embryonic and post-embryonic development of organisms
- Subdivisions:
- Embryology: deals with development of organisms from fertilized egg to formation of form and organs
- Fetology: deals with post-development of embryo to form fetus (prenate)
- Teratology: deals with abnormal or defective (pathological) development
Natural History
- Observational method of study of organisms in their natural environment
- Deals with ways of life and life histories of organisms
Ecology
- Deals with interrelationships of organisms to their physical environment
- Subdivisions:
- Environment at the level of habitat, niche, community, ecosystems, and biomes
Organismal Biology
- Concerned with all aspects of life of organisms
- Study of structure, function, ecology, and evolution at the level of organism
- Subdivisions:
- Morphology: deals with form or shape of organisms revealed as a whole
- Supramolecular Biology: deals with structure and function of biomolecules
Morphology
- Subdivisions:
- Gross Anatomy: deals with internal structures of organisms revealed through dissection
- Histology: deals with study of aggregates of cells or tissues that comprise organs of the body
- Cytology: deals with structure, function, and evolution of cells, the structural and functional units of life
Supramolecular Biology
- Subdivisions:
- Biochemistry: deals with structural configurations and physico-chemical properties of biomolecules
- Molecular Biology: deals with structural and functional properties of biomolecules that comprise genes and body structures
Evolutionary Biology
- Deals with change in the characteristics of a species over several generations
- Relies on the process of natural selection
- Subdivisions:
- Microevolution: deals with evolution on the smallest scale or species level
- Macroevolution: deals with evolutionary patterns and processes above the species level
Paleontology
- Deals with prehistoric organisms identified and recorded as fossils
- Subdivisions:
- Micropaleontology: deals with microscopic fossil organisms
- Paleobotany: deals with fossil plants
- Invertebrate Paleontology: deals with fossil animals without backbones
Test your knowledge on the different subdivisions of Organismal Biology, including Morphology which deals with the form and shape of organisms, and Gross Anatomy which involves studying internal structures through dissection. Learn about the study of structure, function, ecology, and evolution at the organism level.
