Final answer:
The statement 'Dryads are mythological spirits who make their homes in trees' is true. Additionally, while wood is an insulator, lightning can indeed travel through a tree to reach the Earth because of the moisture content within the tree that enhances conductivity.
Step-by-step explanation:
Dryads are indeed mythological spirits according to ancient Greek mythology, who are closely associated with trees, particularly oak trees. They are considered to be nymphs and are often depicted as beautiful maidens who inhabit trees, with each Dryad being connected to a specific tree. The statement 'Dryads are mythological spirits who make their homes in trees' is true.
Although wood is normally an insulator, it's also true that lightning can travel through a tree to reach Earth. This is because lightning seeks a path of least resistance to the ground. The moisture found in a tree enhances its conductivity, allowing lightning to pass through and potentially splitting the tree or causing it to burst into flames.
Moreover, trees are incredibly significant to humans beyond mythology. There are more than 700 living species of trees, many of which, like pines with needle-like leaves, are the dominant plants in their habitats. These trees are greatly valued for their use in producing paper and timber, demonstrating the practical importance of trees in human society.
