Matière vivante, Bactéries
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 spécimen, l’effet de la température sur le métabolisme, la locomotion des micro-organismes, ainsi que pour étudier la respiration des plantes, la photosynthèse, la plasmolyse et plus encore. Les cultures d’algues forment des colonies cellulaires très faciles à visualiser, ce qui permet de mieux comprendre les parois cellulaires et les plastes. De nombreux spécimens vivants se reproduisent rapidement, ce qui facilite un enchaînement rapide des tests successifs.
