There are so many odd trees in this park
How can a three form like this?
An evolutionary adaption to treehouses? Something else?
<It has to do with the distance from the apical meristem.
<The apical meristem holds a lot of stem cells within the growing plant, and is generally the top of the forming tree/bush. The trunk of a tree is the remnants of the apical meristem as the tree grows in height.
<One of the hormones it releases is called auxin. When auxin is released into the vascular system of the plant, it contributes to apical dominance, which prevents any branches from growing below. Thus, auxin is a negative feedback hormone; if concentrations are high, things are prevented from happening. As the apical meristem moves higher, the concentration of auxin becomes lower, and this triggers secondary meristems that have formed to branch out. Basically, as the tree gets taller, the auxin concentration at the secondary meristems is lower, and they grow out.
Now I know! Thanks Bernd
This is probably true, but I read a story that has a better explanation.
Trees are greedy fucks. When they start off they grow taller thinking they need to outgrow other trees, but what if they're alone? They grow out and all around, to prevent other plants and sunflowers from competing. And so it is that trees became hated by the rest of the plant kingdom.
