Trees have big and long trunks so that they can stand erect in worst climates
lke earthquakes , floods , very fast blowing winds etc.
In tropical rain forests trees become tall in search of more sunlight.
Trees have branches because as they grow, parts of the tree grow into smaller parts. These are called branches. Each specie of tree has its own development of branches.
The role of the trunk of a tree is to keep everything together, its what keeps the limbs attached to the tree and is the gateway for the roots too give the limbs of the tree nutrition.
branches
The tree trunks are cylindrical because they grow from the center and outwards. They grow uniformly and this is evident from the rings when the trees are cut.
The mangrove trees can have many trunks, but the banyan tree has both multiple trunks and above-ground "prop roots" that can grow vertically and horizontally.
because the tall trees would be more spread apart
Trees show growth rings on the cross-section of their trunks.

Tree trunks are straight and branchless Tree trunks are straight and branchless in the rainforest because, so that they can grow tall. As their efforts can be on growing tall not having branches near the bottom. More water falls down on the top of the tree. Therefore,they put their efforts in growing tall so that gain most water. Simply, the trees are close together and grow towards the light only the tops receive light so the lower branches die off because of lack of the aforesaid light. The water supply to the trees is drawn up by the roots.
