We don't know what a tree is (and this video won't tell you)

The video explores the complexity of defining what constitutes a tree. It highlights the inadequacy of using physical characteristics, such as having a single woody trunk, to define trees, as exceptions like palm and banana trees exist. The video also examines taxonomy, revealing that genetic relationships do not provide a clear definition either, as trees like oaks and pines are not closely related. Ultimately, the video concludes that there is no universal definition of a tree, emphasizing the complexity and messiness of nature and language.

Which of the following plants challenges the traditional definition of a tree due to its trunk composition?

• Cedar tree

• Maple tree

• Palm tree

• Oak tree

What is the main reason taxonomy fails to define what a tree is?

• Trees are all genetically identical.

• Trees are more closely related to non-tree plants.

• All trees have the same physical characteristics.

• Taxonomy only classifies animals.

Which of the following is more closely related to an oak tree than a pine tree?

• Aspen

• Orchid

• Maple tree

• Cedar tree

What does the video suggest about the evolution of 'tree-ness'?

• It is exclusive to tropical regions.

• It evolved once in a single location.

• It evolved multiple times in different places.

• It is a recent evolutionary development.

What is the main takeaway regarding the definition of a tree?

• Taxonomy provides a clear definition of a tree.

• All trees are genetically identical.

• There is no universal definition of a tree.

• Physical characteristics are sufficient to define a tree.
