Explanation:

Prokaryotes do have organelles, but not complex, membrane-bound organelles. As a result, the membrane-bound mitochondria would certainly not be seen in prokaryotes. Remember that plants are eukaryotes, and also have cell walls similar to prokaryotes. In addition, prokaryotes have ribosomes and DNA.

You are watching: Which of the following structures is not found in prokaryotic cells?


Explanation:

Prokaryotes perform not have membrane-bound organelles, such together mitochondria or an endoplasmic reticulum.

Flagella room hair-like structures that permit the cell to move, and also are current in both prokaryotes and eukaryotes. Although prokaryotes don"t have actually multiple chromosomes choose eukaryotes, they execute still have DNA in the type of a cyclic chromosome. Ribosomes room not bound by a membrane, and are crucial to the process of translation, which creates proteins in the cell. Prokaryotes and also eukaryotes possess ribosomes in bespeak to kind functional proteins.

Example inquiry #2 : Cell frameworks


Where walk the electron carry chain take place in prokaryotes cells and eukaryotic cells, respectively?


Possible Answers:

The chloroplasts; the mitochondria


The mitochondria; the mitochondria


The to move membrane; the mitochondria


The chloroplasts; the moving membrane


The mitochondria; the to move membrane


Correct answer:

The moving membrane; the mitochondria


Explanation:

Prokaryotes, such as bacteria, carry out not save membrane-bound oribel such together the nucleus, mitochondria, and also chloroplasts that we might find in a eukaryotic bio cell. Because we know the electron deliver chain (ETC) is essential in giving cellular energy, prokaryotes must still perform some type of this process. The complexes the the and so on are found in the actual cellular membrane the separates the cabinet from the environment in prokaryotes, while castle are uncovered in the inner mitochondrial membrane in eukaryotes. Eukaryotes are then maybe to create a proton gradient in between the two mitochondrial membranes within the intermembrane space, if prokaryotes can generate a gradient in between the cabinet membrane and also cell wall.

Example question #4 : knowledge Eukaryotic and Prokaryotic differences


Prokaryotes and also eukaryotes are characterized by a collection of differences. I m sorry of the complying with structures is discovered in one course of cell, but not the other?


Possible Answers:

Plasma membrane


Mitochondria


Ribosomes


Cell wall


Correct answer:

Mitochondria


Explanation:

Prokaryotes carry out not have membrane-bound organelles, so they would not have actually mitochondria.

Cell walls and plasma membrane are discovered in both bacteria (prokaryotes) and also plants (eukaryotes). Ribosomes room not bound by a membrane, and also are greatly composed that rRNA; they are used for protein synthetic in both prokaryotes and eukaryotes.

Example concern #5 : knowledge Eukaryotic and Prokaryotic differences


Which framework is existing in prokaryotes cells, but not eukaryotic bio cells?


Possible Answers:

A cabinet membrane


80S ribosomes composed of one 60S and one 40S subunit


A circular, double-stranded molecule of DNA together its main genetic material


Numerous organelles like mitochondria and also lysosomes


A nuclear envelope


Correct answer:

A circular, double-stranded molecule the DNA as its main hereditary material


Explanation:

In general, prokaryotic cells are smaller and less complicated than eukaryotic cells. They lack membrane-bound organelles (such together mitochondria) and also contain a nucleoid region instead of a membrane-bound nucleus. Castle do have actually ribosomes, yet those are small (70S) and also composed that one 30S and one 50S subunit. Only eukaryotic ribosomes room 80S. Finally, both prokaryotes and eukaryotes are encased in cabinet membranes.

One difference between prokaryotic and eukaryotic cells is the organization and storage of genetic material. Both usage DNA in the double-helix structure. In eukaryotes, this DNA is stored as chromatin or chromosomes in ~ the nucleus, yet in prokaryotes that is save in a circular bundle recognized as the newly closed in the cytoplasm.

Example concern #6 : expertise Eukaryotic and also Prokaryotic distinctions


Prokaryotic cells have actually __________.


Possible Answers:

a newly closed region, however no plasma membrane encasing the cell


a plasma membrane encasing the cell, however no membrane-bound organelles


mitochondria, yet no nucleus


a Golgi apparatus, yet no membrane-bound nucleus


a membrane-bound nucleus, but no lysosomes


Correct answer:

a plasma membrane encasing the cell, yet no membrane-bound organelles


Explanation:

When comparing prokaryotes to eukaryotes, the main truth to psychic is the prokaryotes carry out not contain membrane-bound organelles. This means they have no mitochondria, Golgi apparatus, or absorbent reticulum. They also lack a membrane-bound nucleus, back they do have genetic material located in a new closed region. Prokaryotes cells space surrounded through a plasma membrane, and some types of bacteria have actually cell wall surfaces as well.

Example concern #7 : knowledge Eukaryotic and Prokaryotic distinctions


Which structure can be found in a prokaryotic cell?


Possible Answers:

Peroxisomes


Rough endoplasmic reticulum


Plasma membrane


Mitochondria


Centrioles


Correct answer:

Plasma membrane


Explanation:

Prokaryotic cell differ from eukaryotic cells in that they lack any kind of membrane-bound organelles, consisting of a nucleus. Instead, prokaryotes cells simply have actually an outer plasma membrane, DNA newly closed structure, and ribosomes.

Rough endoplasmic reticulum, peroxisomes, and also mitochondria space all bound by their own plasma membranes, and also are only discovered in eukaryotic bio cells. Centrioles are a ingredient of the cytoskeleton of eukaryotic cells, however are not found in prokaryotes.

Example inquiry #1 : Cell frameworks


A group of researchers in a activities have uncovered what they think to it is in an unknown organism. They notice that this organism lacks a atom membrane and mitochondria. Utilizing this information, i beg your pardon of the complying with structures would certainly this biology most most likely possess?


Possible Answers:

Lysosomes


Chloroplasts


Endoplasmic reticulum


Cilia


Ribosomes


Correct answer:

Ribosomes


Explanation:

The organism is likely a prokaryotes organism, because it lacks a nuclear membrane and also mitochondria. Prokaryotes lack all membrane-bound organelles, including nuclei, mitochondria, absorbent reticulum, chloroplasts, and also lysosomes.

Both prokaryotes and also eukaryotes save on computer ribosomes. Ribosomes are not membrane-bound, and are mostly composed of rRNA. Prokaryotes need ribosomes in order come synthesize proteins.

Cilia are composed of microtubules. While countless prokaryotes have cilia, we cannot draw any conclusions without knowing much more about the identification of the organism.

Example question #9 : knowledge Eukaryotic and Prokaryotic distinctions


A prokaryotic cell consists of which the the following? 


Possible Answers:

Ribosomes


Endoplasmic reticulum 


Golgi apparatus 


Microtubules 


Nucleus 


Correct answer:

Ribosomes


Explanation:

Prokaryotic cell are basic cells that lack membrane-bound nuclei and complicated organelles. Absorbent reticulum, microtubules, and also the Golgi apparatus are distinctive to eukaryotic cells, and also will no be found in prokaryotes. Prokaryotes do, however, save on computer ribosomes, though smaller than the ribosomes in eukaryotic bio cells. Prokaryotes and also eukaryotes space both capable of the main processes of the main dogma: DNA replication, transcription, and translation. Because that this to it is in possible, prokaryotes must contain DNA, transcription proteins, RNA, and ribosomes.

Example question #10 : knowledge Eukaryotic and also Prokaryotic distinctions


What structure have the right to be found in all living cells?


Possible Answers:

Mitochondria


Nucleus


Nucleolus 


Cell wall


Ribosomes


Correct answer:

Ribosomes


Explanation:

Unlike eukaryotes, prokaryotes have no membrane-bound organelles. This means that they absence a nucleus, mitochondria, and also other progressed cell structures.

All cells count on protein materials in order come function. Protein synthesis takes place on ribosomes, which deserve to be uncovered in every cell types. In prokaryotes, ribosome are free floating the cytoplasm; in eukaryotes, ribosomes have the right to be free floating in the cytoplasm, bound to the rough absorbent reticulum, in mitochondria, or in chloroplasts.
