They typically have a circular chromosome. They lack a plasma membrane.<\/strong><\/p>\n\n\n\n<p>Explanation:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Circular Chromosome<\/strong>: Prokaryotic cells do indeed typically have a circular chromosome. This chromosome is located in a region called the <strong>nucleoid<\/strong>, not enclosed within a membrane-bound nucleus, as in eukaryotic cells.<\/li>\n\n\n\n<li><strong>Lack of Plasma Membrane<\/strong>: This part of the statement is incorrect. <strong>Prokaryotic cells<\/strong> do <strong>have<\/strong> a plasma membrane. The plasma membrane is a crucial structure that surrounds the cell and regulates the movement of substances in and out of the cell. It plays a similar role in prokaryotic cells as it does in eukaryotic cells. In fact, all cells, whether prokaryotic or eukaryotic, have a plasma membrane. So, the claim that prokaryotes &#8220;lack a plasma membrane&#8221; is factually wrong.<\/li>\n<\/ul>\n\n\n\n<p>Now, let&#8217;s look at the other options:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>B. They reproduce by binary fission<\/strong>: This is <strong>correct<\/strong>. Prokaryotic cells reproduce asexually by binary fission, where the cell divides into two identical daughter cells. This process involves the duplication of the chromosome and the division of the cytoplasm.<\/li>\n\n\n\n<li><strong>C. They lack membrane-enclosed organelles<\/strong>: This is <strong>correct<\/strong>. Prokaryotic cells do not have membrane-bound organelles such as mitochondria, endoplasmic reticulum, or the Golgi apparatus. They do, however, have ribosomes, which are not membrane-enclosed.<\/li>\n\n\n\n<li><strong>D. Their DNA is not enclosed within a membrane<\/strong>: This is <strong>correct<\/strong>. In prokaryotic cells, the DNA is typically found in the <strong>nucleoid<\/strong>, which is an area of the cell where the genetic material is concentrated but not enclosed by a membrane. This contrasts with eukaryotic cells, where DNA is enclosed within a membrane-bound nucleus.<\/li>\n<\/ul>\n\n\n\n<p>Thus, <strong>A<\/strong> is the only incorrect statement because it misrepresents the presence of the plasma membrane in prokaryotic cells.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Which of the following statements is INCORRECT regarding prokaryotic cells?
