Se hela listan på courses.lumenlearning.com One of the simplest divides life into prokaryotes and eukaryotes; that is, those organisms without nuclei went into one group and those with nuclei went into another, respectively. Another commonly used scheme divides life into five kingdoms: Monera (prokaryotes), Protista, Plantae, Fungi, and Animalia. This is a simplified answer to the question: What is the basis for dividing prokaryotes into two domains? Microbiologists noted a long time ago that not all “bacteria” had the same membrane lipids. 2020-01-29 · Prokaryotes are organisms made up of cells that lack a cell nucleus or any membrane-encased organelles.
Bacteria and archaea are differentiated in virtue of their cell structure and specific evolutionary history. 1. "Domains Archaea and Bacteria" is the one among the following choices given in the question that contain only prokaryotes.

Which two Domains contain organisms that do not have a nucleus in their cells ? archaea & Eubacteria have a cell wall andare prokaryotic. 2.
Prokaryotes do not undergo mitosis; instead, the chromosome is replicated and the two resulting copies separate from one another, due to the growth of the cell. The prokaryote, now enlarged, is pinched inward at its equator and the two resulting cells, which are clones , separate. Binary fission is a type of cell division in which a parent cell copies it’s genetic material, and then divides, transforming into two daughter cells, each new cell having one complete copy of the genetic instructions necessary to run the cell.
