Like how do they know to start germinating? Especially ones that have to survive extreme environments for years and years. Doesn’t it take energy to keep sensing those conditions? Couldn’t those conditions destroy their sensors?
In: Biology
Each plant has a set of requirements before germination. Some (most?) require a certain ground temperature. Many require a certian amount of time being frozen before they germinate. I have heard of an evergreen tree that requires their seed to burn before they germinate (the fire clears debris and gives the saplings room to grow)
It isnt so much that the plant has sensors, more like the plant needs certian criteria met. And the seed has some oil in it, making it less likely to freeze or dry up.
