在地球引力场内,草履虫能够正常生长,当它遇到恶劣条件时(如低温、缺水等),就形成胞囊来保护自己。那么,在无引力的情况下,草履虫能否正常生长繁殖呢?本实验用离心、干燥法保存草履虫胞囊,密封瓶盛稻草水培养草履虫,利用小灯泡为革履虫供光、供热,用福尔马林固定实验结果,在航天飞机返回后进行镜检计数,以确定失重情况下草履虫的生长繁殖情况。
In the gravitational field of the earth, Paramecium can grow normally, and when it encounters bad conditions (such as low temperature, water shortage, etc.), it forms cysts to protect itself. So, in the absence of gravitation, Paramecium normal growth and reproduction it? In this experiment, centrifugal, drying method to save cells of metokidokiae, sealed bottles of straw water culture Paramecium, the use of small bulbs for Paramecium light for Heat, with formalin fixed experimental results, the shuttle returned after the microscopic count to determine the growth and reproduction Paramecium weightlessness case.
