Study Notes
Overview of Biology Subfields
Biology encompasses several interconnected subdisciplines, each representing distinct aspects of the study of life. At the broadest scale, organisms can be categorized by their size, ranging from molecules (cell biology) through cells (genetics) to ecosystems (ecology), and extending further to populations, communities, and biosphere (evolution). Physiology focuses on the function of individual components of living systems and their interactions, providing insights into the processes that sustain life across scales.
Cell Biology
Cell biology investigates the fundamental units of life, the cells, examining their structures, functions, behaviors, relationships, and contributions to overall organismal functioning.
Genetics
Genetics studies heritable traits passed between generations, exploring genetic variation, transmission, mutation, recombination, gene expression, epigenetic regulation, Mendelian inheritance patterns, and population genetics.
Ecology
Ecology concerns the relations between living creatures and their environment, considering factors like energy flow, nutrient cycles, community dynamics, and ecosystem stability.
Evolution
Evolution deals with changes over time in the genetic makeup of populations due to natural selection, gene flow, genetic drift, and mutation. It explains the diversity of life forms and adaptive responses to environmental challenges.
Physiology
Physiology encompases diverse subjects including animal behavior, plant growth, nutrition, reproduction, respiration, circulation, excretion, sensitivity, and nerve impulses. It seeks to explain how individual cells, tissues, and organs interact to carry out life's essential activities.
Each of these subfields contributes to a holistic understanding of biology, underscoring the intricate connections among seemingly disparate phenomena in life sciences.
