Textbook Question

Select any of the following characteristics that would NOT apply to prokaryotes. (NCLEX/HESI/TEAS)
a. Generally simpler than eukaryotes
b. Multicellular
c. Lack a true nucleus
d. Tend to have a single circular chromosome
e. Often lack a cell wall
f. All make endospores
g. Divide by mitosis
h. Includes the Domain Archaea
i. Includes the Domain Bacteria
j. Includes the Domain Eukarya

Verified step by step guidance

Identify the characteristics of prokaryotes: Prokaryotes are generally simpler than eukaryotes, lack a true nucleus, tend to have a single circular chromosome, and include the Domains Archaea and Bacteria.

Understand that prokaryotes are unicellular organisms, so they are not multicellular.

Recognize that prokaryotes do not divide by mitosis; instead, they reproduce through binary fission.

Note that not all prokaryotes make endospores; only certain bacteria, like Bacillus and Clostridium, have this capability.

Realize that prokaryotes often have a cell wall, although the composition can vary, such as peptidoglycan in bacteria and pseudopeptidoglycan in some archaea.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Prokaryotic vs. Eukaryotic Cells

Prokaryotic cells are generally simpler and smaller than eukaryotic cells. They lack membrane-bound organelles and a true nucleus, with their genetic material organized in a single circular chromosome. In contrast, eukaryotic cells have a defined nucleus and complex structures, often forming multicellular organisms.

Characteristics of Prokaryotes

Prokaryotes, which include the Domains Bacteria and Archaea, typically possess a cell wall and reproduce asexually through binary fission, not mitosis. They can form endospores for survival in harsh conditions, but they do not have multicellular forms, which is a characteristic of many eukaryotes.

Domains of Life

Life is classified into three domains: Bacteria, Archaea, and Eukarya. Prokaryotes are found in the Bacteria and Archaea domains, while Eukarya includes all eukaryotic organisms. Understanding these domains is crucial for distinguishing the fundamental differences between prokaryotic and eukaryotic life forms.
