The number of children per node in a tree is determined by the type of tree. Different types of trees have distinct definitions that dictate how many children each node can have. For instance, a binary tree allows each node to have at most two children, while a ternary tree permits up to three children. Understanding the structure imposed by the type of tree is crucial for analyzing the way nodes are connected and how data is organized within the tree.

The order of insertion does not influence the maximum number of children a node can possess; it pertains to how nodes are added to the tree. Similarly, the height of the tree relates to the longest path from the root to a leaf and does not dictate the number of children per node. Lastly, the values of the nodes help in comparing and sorting data but do not define the tree's structural rules regarding children. Therefore, the determination of the number of children each node can have is fundamentally based on the specific tree type in use.
