There are many reasons why tree shapes differ. A tree growing in poor soil may be stunted due to lack of nutrients, and a tree growing right next to an apartment building may have more leaves on the side facing the sun..
Furthermore, why do leaves have different shapes?
The shape of a tree's leaves are a response to the tree species' long term ecological and evolutionary histories. A leaf must take in carbon dioxide from the surrounding air via pores (called "stomatae"). This carbon dioxide is also needed for photosynthesis.
Beside above, why are trees round? A round or tubular shape allows them to resist the force of the wind better than the flat surface of a square or rectangle would. Not only does its round shape help resist the wind, but it also is a very strong shape that helps support a lot of branches. We evolved into the shape we are because it works well for us.
Similarly, you may ask, what is the shape of a tree?
Most deciduous trees have less dominant shapes, but each is distinctive in its own way. The basic growth habits of trees are columnar, weeping, pyramidal, horizontal branching, vase shaped, round headed or globe shaped.
Why are pine trees shaped like triangles?
Evergreen trees – which are known collectively as conifers – often grow in places that have severe winters. An evergreen tree's shape does help keep wet, heavy snow off its upper branches. The tree's shape also lets it get more light, because the top branches don't shade the bottom ones.
