At one time, all living organisms were separated into only two kingdoms—Animals and Vegetables. Once the microscope was invented and improvements in microscopy were made, however, more kingdoms were defined. The Protist kingdom was established in 1866, and the Monera kingdom was added in 1938.The Monera kingdom was later subdivided into the Eubacteria and Archea kingdoms in the1990s. Fungi were classified as plants until 1969. What is one reason why fungi were separated into a new kingdom? (1 point) Responses All fungi are unicellular. All plants are multicellular.

Answer 1

The correct response is: The cell walls in fungi are composed of chitin. Plant cell walls are composed of cellulose.

This distinction in cell wall composition is one of the key reasons why fungi were classified into their own kingdom, separate from plants.
