Model organisms are widely studied species or strains used for biological research due to their easy maintenance and breeding. Examples include E. coli, which is a prokaryotic model organism, and Drosophila melanogaster, used for animal genetics. Other examples are Saccharomyces cerevisiae for eukaryotes and Arabidopsis for plant studies, all characterized by simple morphology and rapid breeding times.

1. 3. We learn a lot of information from model organisms. Frequently, these model organisms have
a particular “specialty” – a particular field within biology for which the organism has provided a
lot of information. Name 2 model organisms and tell what the “specialty” of each is.
Solution
Model organism is a species or strain that has been widely studied, because of easy maintenance,
easy breeding in the lab and possess experimental advantages.
E. coli is Gram - ve prokaryotic model organism
Drosophila melanogaster is, model organisms for Animal genetics
Saccharomysis cereveciae or yeast is a model organism for Eukaryotes
Arabidopsis is model organisms for plant studies
All these model organisms possess simple morphology, less genome size, less breading time,
mostly related to higher organisms etc
