病毒不算微生物。它是细菌的1/1000,连细胞都没有。生物都能单独存在,病毒只能成为别人的一部分,就好像 ...
The viruses pose a problem. Some biologists would say that viruses were not alive because they do not have cells, rather they refer to them as biological agents. The term biological agent relates to the major effects they have on the organisms that they infect, but the lackvof a cell, buy this definition, puts them outside the groupvof living things.
other bioloists argue that because viruses can reproduce and there is a genetic consistency in their offspring that they possess a common characteristic with all other living things. These biologists would regard viruses as living things even though they do not have cells.
病毒是有争议的一个话题,究竟算不算活物,区别在于它们没有细胞形态,但是它们和其他微生物有共性,都可以繁殖,后代存在遗传一致性,所以也有不少生物学家将它们视为活物,生物。 |
