Les spécimens vivants sont utilisés dans une grande variété d’études, notamment pour observer les effets physiologiques des médicaments sur le rythme cardiaque d’un organisme, l’influence de la température sur le métabolisme, la locomotion des organismes microscopiques, ainsi que la respiration des plantes, la photosynthèse, la plasmolyse et bien plus encore. Les cultures d’algues forment des colonies cellulaires très faciles à visualiser pour mieux comprendre les parois cellulaires et les plastes. De nombreux spécimens vivants se reproduisent rapidement, permettant un renouvellement rapide entre les tests successifs.
