Trees are not all the same. Many trees have a unique shape and structure, and every tree spawns in different biomes. All bricks have the same shape, and they may only be generated in certain structures, in which case the structure article will mention it. A brick is maybe 3-5 lines of code, a tree has a whole class that defines its structure PLUS a few extra lines of code. You can think of a tree like a special type of structure, and that's indeed what trees are in the code.
