How are Plants, Fungi, and Animals related? (list 2 ways)
Animals and Fungi have been found to be more closely related.
Using molecular data and phenotypic traits.
While Fungi have rigid walls like plants - they are primarily made of chitin which is found in arthropod skeletons.
Fungi may look similar to plants but they do not have chlorophyll and cannot make their own food.
