Matière vivante, Aquariums

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