wwclqParticipantIt is said that when Azotobacter vinelandii faces a difficult situation ,it can have some thing like a spore ,which called "cyst". So,what are the differences between them? And how can they make such changes？

I guess you mean spores. These are highly resistant to either dryness, irradiance, lack of nutrients etc., but they do not grow nor divide, so they cannot compete with other, active cells 😉

Thanks.And,how does it work？I mean,how can a cyst resist dryness?(seems that it is resistant to dryness only)

if you’re dead-like, you don’t need water 😉 And if you have enough mechanisms to repair your DNA, you can be quite fine even after dryness 🙂
