A concise overview of key concepts in biology, particularly focusing on evolution and genetics. It defines terms such as population, transitional features, vestigial traits, homologous and analogous structures, biogeography, and phylogeny. Additionally, it covers various aspects of natural selection, including directional, stabilizing, and disruptive selection, as well as genetic drift and gene flow. The document also touches on allele and genotype frequencies, hardy-weinberg equilibrium, and different modes of speciation like allopatric and sympatric speciation. It further explains plant biology concepts such as indeterminate and determinate growth, root and shoot systems, and various plant structures and adaptations. This resource is valuable for students seeking a quick review of essential biological terms and concepts, offering clear definitions and explanations to aid in understanding complex topics.
