黑藻是观察细胞质流动的最佳活体材料,它的习性是生活在净水池沼中。近年来,由于许多池沼被污染,使黑藻赖以生存的条件被破坏,造成采集很困难,也使这种活体材料得来不易。为了保证实验顺利进行,我们考虑到,既然草履虫、水螅能够进行实验室培养并获得成功,那么,黑藻是否也可以进 Black algae is the best living material for observing the flow of cytoplasm, and its habit is to live in a clean sink. In recent years, because many ponds have been contaminated, the conditions for the survival of black algae have been destroyed, making collection difficult and making this living material difficult to obtain. In order to ensure the smooth conduct of the experiment, we have considered that if Paramecium and Hydra are able to undergo laboratory cultivation and success, then can Black algae also
