WebMany prokaryotes have more than one cell membrane- and outer an inner membrane. The outer membrane often includes large pores that are large enough allow "goodies" such as sugars and amino acids drift into the intermembrane space. The inner membrane does not include these pores, and we'll discuss transport across these membranes in a later … WebSelect the TWO answers that are correct. A.) Prokaryotic cells have a nucleus, whereas eukaryotic cells do not. B.) Prokaryotic cells use RNA, whereas eukaryotic cells use DNA. C.)

WebWhy do prokaryotic cells not have a membrane? Prokaryotic cells do not have a nucleus. The genetic material for prokaryotes is concentrated in a region called the nucleoid but there is no membrane separating this region from the rest of the cell unlike in eukaryotic cells, which do have membrane-bound nuclei. Animal cells and plant cells … WebJul 28, 2024 · Prokaryotes are unicellular organisms that lack membrane-bound structures, the most noteworthy of which is the nucleus. While prokaryotic cells do not have membrane-bound structures, they do have distinct cellular regions. In prokaryotic cells, DNA bundles together in a region called the nucleoid. science and everyday life cannot and should
