The Kingdom Monera has been separated into two domains, the Archaea and the Bacteria. Which of the following was most important in prompting scientists to change the way these organisms were classified?
a.)Major differences were discovered in the structure and operation of the different species of Monera.
b.)So many new species of Monera were discovered that the kingdom got too large and needed to be separated.
c.)Advances in technology revealed that some species of Monera had nuclei and some did not.
d.)Some species of Monera were found that could live in colonies rather than as single cells.
a.)Major differences were discovered in the structure and operation of the different species of Monera.
ARE YOU SURE?
c.) Advances in technology revealed that some species of Monera had nuclei and some did not.
The correct answer is a.) Major differences were discovered in the structure and operation of the different species of Monera.
To understand why this answer is the most important in prompting scientists to change the classification of Monera, we need to understand the context. The Kingdom Monera was originally established to include all prokaryotic organisms, which are single-celled organisms lacking a nucleus or membrane-bound organelles. However, as scientific knowledge advanced, scientists discovered significant differences within the Monera that questioned the validity of grouping them together.
By studying the structure and operation of different species of Monera, scientists started to uncover distinct characteristics and fundamental differences between them. These differences extended to aspects such as their cellular structure, metabolic processes, genetic makeup, and other key features. These findings indicated the existence of multiple distinct groups within the Kingdom Monera, which could not be adequately explained or accounted for under a single classification.
Therefore, the major differences discovered in the structure and operation of different species of Monera led scientists to reassess their classification and eventually separate Monera into two domains: Archaea and Bacteria. This division allowed for a more accurate representation of the diversity and complexity of these organisms.
