Live Specimens
Live specimens are used for a wide variety of studies including studying the physiological effects of drugs on a specimen’s heartbeat and temperature on metabolism, the locomotion of microscopic organisms, and studying plant respiration, photosynthesis, plosmolysis, and more. Algal cultures form colonies of cells that are extremely easy to visualize for better understanding of cell walls and plastids, and many live specimens reproduce rapidly for quick turnover between successive tests.

Drosophila Sets, Live Fruit Flies
Supplier: Avantor
Drosophila melanogaster, the common fruit fly, is widely used in genetic studies. They express a number of mutations such as eye, wing, and body mutations. Students can study sex-linked, recessive, and dominant mutations. Drosophila also makes an excellent live food for mantises, small reptiles, and amphibians. Drosophila demonstrates complete metamorphosis with egg, larva, pupa, and adult stages in its life cycle.
