Based on the table, which domains contain only one body type?
A. Fungi and Eukarya
B. Bacteria and Archaea
Answer (1)
Bacteria domain has only one body type: Unicellular.
Archaea domain has only one body type: Unicellular.
Eukarya domain has multiple body types: mostly unicellular, both, and multicellular.
The domains that contain only one body type are Bacteria and Archaea. B a c t er iaan d A rc ha e a
Explanation
Understanding the Problem We are given a table that classifies kingdoms by domain, body type, and cell type. Our task is to identify which domains contain only one listed body type.
Analyzing Each Domain Let's examine each domain:
Bacteria: The table shows that the Eubacteria kingdom, which falls under the Bacteria domain, has a unicellular body type. Thus, the Bacteria domain has only one body type: Unicellular.
Archaea: The table shows that the Archaebacteria kingdom, which falls under the Archaea domain, has a unicellular body type. Thus, the Archaea domain has only one body type: Unicellular.
Eukarya: The kingdoms Protista, Fungi, Plantae, and Animalia fall under the Eukarya domain. These kingdoms have body types of mostly unicellular, both, multicellular, and multicellular, respectively. Thus, the Eukarya domain has more than one body type.
Identifying the Domains Therefore, the domains that contain only one body type are Bacteria and Archaea.
Examples
Understanding how organisms are classified into domains based on their cellular and body characteristics helps us trace their evolutionary relationships. For example, knowing that Bacteria and Archaea consist of only unicellular organisms, while Eukarya includes both unicellular and multicellular organisms, provides insights into the complexity and diversity of life forms. This classification is crucial in fields like medicine, where identifying the domain of a pathogen (e.g., bacteria) informs treatment strategies, or in environmental science, where understanding the roles of different domains in ecosystems is essential for conservation efforts.
