| From the perspective of physical structure, a tree is a data structure based on linked lists, hence its traversal method involves accessing nodes one by one through pointers. However, a tree is a non-linear data structure, which makes traversing a tree more complex than traversing a linked list, requiring the assistance of search algorithms to achieve. | |||

'From a physical structure perspective, trees are data structures based on linked lists.' --> 'From a physical structure perspective, a tree is a linked-list-based data structure.'
"Tree" refers as a data structure, using the plural form feels incorrect

This paragraph is discussing one specific data structure—a tree. It is not referring to multiple trees or instances of trees, so maybe the singular form should be sufficient.
