Plant growing

[Tropics817]

What makes plants stop growing when they reach their maximum growth?

[Dr.Stein]

Are they stop growing? I don't think so

For a general explanation, their growth is infinite. Maybe you are talking about the ones that just have primary structured organs, that's why some don't grow any further. So some plants flower during some seasons and then die.
Were you talking about them?

I think he was talking about plants that live more than one year, like trees. Trees will grow to a certain hight and then stop, even if they continue to live for a long time afterwards. It is embeded in their DNA
