Prokaryote vs eukaryote quiz
Prokaryotic vs eukaryotic: the differences | cells | biology
Explanation: Prokaryotic and eukaryotic cells have similar structures. A plasma membrane, ribosomes, cytoplasm, and DNA are found in every cell. The plasma membrane, also known as the cell membrane, is a phospholipid layer that covers and protects the cell from the outside world. Ribosomes are non-membrane bound organelles that produce proteins in a process known as protein synthesis. The cytoplasm consists of all of the contents of the cell that are contained within the cell membrane, except the nucleus.
Prokaryotic cells lack a true nucleus as well as the majority of other cell organelles. Prokaryotes are unicellular species that have prokaryotic cells. Prokaryotes include bacteria and archaea.
The nucleus includes ‘nucleoplasm’ (nucleus sap) or karyoplasm, which is similar to the cytoplasm of a cell (protoplasm). The nucleoplasm is a type of protoplasm that is encased by the nuclear membrane, also known as the nuclear envelope. The chromosomes and nucleoli make up the nucleoplasm.
The larger subunit of the 70S ribosome in prokaryotes is 50S, which is approximately equal to the 60S ribosomal subunit in eukaryotic cells. The 50S subunit is mainly made up of proteins, but it also includes ribosomal RNA, which is a single-stranded RNA (rRNA).

Prokaryotic and eukaryotic cell – must do 40
Prokaryotes comprise both Archaea and Bacteria members. They’re among the tiniest species, with diameters ranging from 0.5 to 2.0 microns. The ratio of surface to volume is 12:4. They come in a number of forms, including circular in the case of coccus, rodlike in the case of bacillus, and comma in the case of vibrio. Other shapes include triangular, wavy, cork-screw, and other variations. Prokaryotic cells can be used in a number of configurations. They can be found in pairs, like Enterococcus spp., in chains, like Streptococcus, or in tetrads, like Streptococcus. They can also be found in clusters that look like grapes (staphylo-).
The diameter of eukaryotic cells is greater than that of prokaryotic cells, with the former reaching a diameter of more than 10 microns. Eukaryotic cells are found in all members of the kingdoms Protista, Plantae, Fungi, and Animalia. Here is a detailed explanation of the structure of a eukaryotic cell:
Prokaryotic vs. eukaryotic cells (updated)
Prokaryotes have organelles, but they are not complex membrane-bound organelles. As a result, prokaryotes may not have membrane-bound mitochondria. Plants are eukaryotes, which means they have cell walls like prokaryotes. In addition to DNA, prokaryotes have ribosomes.
Flagella are hair-like structures found in both prokaryotes and eukaryotes that allow the cell to move. Prokaryotes, unlike eukaryotes, do not have multiple chromosomes, but they do have DNA in the form of a cyclic chromosome. Ribosomes are not membrane-bound and are needed for the process of translation, which results in the production of proteins in the cell. Ribosomes are used in both prokaryotes and eukaryotes and are used to make functional proteins.
Explanation: Prokaryotes, including bacteria, lack membrane-bound organelles like the nucleus, mitochondria, and chloroplasts that are present in eukaryotic cells. Prokaryotes must still conduct some form of the electron transport chain (ETC) since we know it is critical in providing cellular energy. In prokaryotes, the ETC complexes are located in the cellular membrane that separates the cell from the environment, while in eukaryotes, they are found in the inner mitochondrial membrane. Prokaryotes can generate a proton gradient between the cell membrane and the cell wall, while eukaryotes can generate a gradient between the two mitochondrial membranes inside the intermembrane space.
