Biology question? Answered
My neighbour cut down a tree last year, down to the ground. This year it sprouted shoots again from the cut edge.
My question is by what mechanism did the remains of the tree "know"
1. It had been cut off and should produce new shoots if it wanted to survive,
2. When to start producing these shoots.
i realise it is triggered by day length and temperature rising BUT how does the tree measure these things?
