Final answer:
The statement is completely false. The common classifications of fungi are not based on appearance, but on phylogenetic relationships.
Step-by-step explanation:
The common classifications of fungi, including mold, yeast, and mushrooms, are not based solely on appearance. They are actually based on phylogenetic relationships, which refer to the evolutionary relationships between different organisms.
For example, fungi are classified into different phyla such as Chytridiomycota, Zygomycota, Ascomycota, Basidiomycota, and Glomeromycota. These classifications are based on their genetic similarities and evolutionary history.
So, the statement that the classifications of fungi are based on appearance more than phylogenetic relationships is false.
