Trunk-borne fruits are unusual, but include the well-known papaya, the commercially-marketed durian, and the largest of tree fruit, the jackfruit. The location of flowers and fruit on the branches or trunk is likely a response to the need for high levels of water transport, and fruit weight that could not be borne by leafy smaller stems. It is also possible that variants with the fruit in this location benefit from increased transport of their seeds, as fruits are accessible to heavier climbing animals, rather than falling from the trees when ripe.
Tree trunks are straight and branchless in their lower parts in their efforts to grow tall.
A tree usually has fewer trunks than branches. Trunks are the main upright structure of a tree that supports the branches, while branches are the smaller offshoots that grow from the trunk.

Some are, some are not.
Different species of different fruits or plants grow differently. For example, a blueberry tree would grow to about 50cm maximum when a mango tree would grow to about 5m.
Tree trunks are straight and branchless in their lower parts in their efforts to grow tall.
Many plants which are called epiphytes grow on tree trunks. They are adapted to grow there as orchids , lichens etc.
Trees grow from the top of their trunks, where new growth occurs in the form of buds and branches. The trunk itself does not grow longer, but rather thicker as the tree ages.
non-tree fruits most likely means fruits that don't grow on trees, like strawberrys
the roots underneath the trunk let the tree grow
Tree trunks are cylindrical in shape because this structure helps to evenly distribute the weight of the tree's canopy, providing stability against winds and other forces. The cylindrical shape also maximizes the tree's ability to transport water and nutrients from the roots to the leaves efficiently.
