Top 10 Commonly Confused Words in Integrative Biology

Top 10 Commonly Confused Words in Integrative Biology 1. Homologous vs. Analogous One of the most common confusions in biology is between homologous and analogous structures. While both refer to similarities, homologous structures share a common ancestry, indicating evolutionary relationships. On the other hand, analogous structures serve similar functions but do not have a common evolutionary origin. 2. Genotype vs. Phenotype Genotype and phenotype are terms often used in genetics. Genotype refers to the genetic makeup of an organism, while phenotype is the observable physical or biochemical characteristics resulting from that genetic makeup. In simpler terms, genotype is the blueprint, and phenotype is the end product. 3. Endothermic vs. Ectothermic When it comes to temperature regulation, organisms are classified as either endothermic or ectothermic. Endothermic organisms, like mammals, generate their own body heat, while ectothermic organisms, such as reptiles, rely on external sources of heat. So, think of endo as 'internal' and ecto as 'external'. 4. Autotroph vs. Heterotroph Autotrophs and heterotrophs are terms used to describe an organism's source of energy. Autotrophs, like plants, can produce their own food through photosynthesis, while heterotrophs, including animals, rely on consuming other organisms for energy. Autotrophs are the 'self-feeders', while heterotrophs are the 'other-feeders'. 5. Prokaryotic vs. Eukaryotic
