AP Biology help » Cellular biologic » Cell structures » knowledge Eukaryotic and also Prokaryotic differences
Explanation:

The main difference between prokaryotic and also eukaryotic cell is that prokaryotic cells absence membrane-bound organelles and also have circular DNA, while eukaryotic bio cells save membrane-bound organelles and also linear strands of DNA. Since prokaryotic cells lack membrane enclosed organelles, cells do not have actually nuclei. Rather, the cell’s DNA is situated in the nucleoid, a nucleus-like region within the cell. Eukaryotic bio cells generally comprise more complex organisms, such as plants, humans, and animals. Prokaryotic cells generally make up bacteria and smaller organisms. Every cells have actually ribosomes.

Example inquiry #22 : Cell frameworks


Prokaryotes give birth via __________.


Possible Answers:

sexual reproduction


meiosis


mitosis


binary fission


Correct answer:

binary fission


Explanation:

Prokaryotes utilize binary fission because that cellular division. Binary fission involves asexual reproduction the prokaryotes. An initial the cell grows and also duplicates that is genome, and any plasmids. The cell polarizes itself, then begins forming a cell wall to divide the cell into two slightly smaller cells. Eukaryotes usage mitosis, and also meiosis. Sex-related reproduction occurs in some phyla that eukaryotes.

Example inquiry #23 : Cell frameworks


Which the the following lacks a nucleus?


Possible Answers:

Animal cells


Prokaryotic cells


Plant cells


Eukaryotic cells


Correct answer:

Prokaryotic cells


Explanation:

Prokaryotic cells execute not have actually a nucleus. The genetic material for prokaryotes is focused in a an ar called the nucleoid but there is no membrane separating this region from the rest of the cell unlike in eukaryotic bio cells, which do have actually membrane-bound nuclei. Animal cells and plant cells space eukaryotes.

Example concern #24 : Cell structures


Organelles room membrane-bound structures uncovered only in ~ the cells of eukaryotes. These structure administer different functions within the cell. 


Which the the complying with is not taken into consideration an organelle?


Possible Answers:

Ribosome


Chloroplast


Peroxisome


Nucleus


Mitochondria


Correct answer:

Ribosome


Explanation:

All of this structures space organelles except the ribosome. The ribosome is uncovered in both prokaryotic and eukaryotic cells. That is the site of protein synthetic (translation). Ribosomes may be free-floating in the cytoplasm, or attached come the endoplasmic reticulum in eukaryotes. Due to the fact that ribosomes room not membrane-bound, they carry out not to the right the classical an interpretation of an organelle.

Example question #25 : Cell frameworks


Cell walls deserve to be discovered in all of the following groups of organisms except __________.


Possible Answers:

mammals


plants


protists


bacteria


fungi


Correct answer:

mammals


Explanation:

The only team organisms detailed without cabinet walls space mammals. Every one of the various other organisms might or may not have cell walls. For example, part fungi, however not all, have cell walls made of chitin. Bacteria, but not Archaea, have cell wall surfaces made of peptidoglycan, and plants have actually cell wall surfaces made the cellulose. A little subset that protists may also contain cabinet walls.

Example concern #26 : Cell structures


The DNA of prokaryotes cells have the right to only be found in the __________.


Possible Answers:

nucleus


histones


chromatin


nucleolus


nucleoid


Correct answer:

nucleoid


Explanation:

Prokaryotic cells carry out not save on computer organelles (nucleus). They also lack chromosomes; therefore, histones and also chromatin space not present. Finally, the nuclear source is a region of the nucleus whereby ribosomal subunits room assembled. This region is only present in eukaryotic cells. The new closed is a an ar in prokaryotic cells that includes the DNA.

Example inquiry #27 : Cell structures


Which of the complying with can be discovered in a prokaryotes cell?


Possible Answers:

Mitochondria


Ribosomes


Centrioles


Nucleus


Endoplasmic reticulum


Correct answer:

Ribosomes


Explanation:

Prokaryotic cells perform not have actually membrane-bound oribelles or nuclei. However, castle do have ribosomes. Top top the various other hand, centrioles, the absorbent reticulum, the mitochondria, and also the nucleus deserve to all be found in eukaryotic bio cells, yet not prokaryotes cells.

Example inquiry #28 : Cell frameworks


Which of this is not found in prokaryotic cells?


Possible Answers:

Membrane proteins


Cell membrane 


Ribosome


Golgi apparatus


Cytosol 


Correct answer:

Golgi apparatus


Explanation:

Prokaryotes perform not save membrane-bound organelles for this reason they carry out not have actually a Golgi apparatus. Prokaryotic cells have cell membrane that incorporate proteins and also sugars the facilitate the i and/or exclusion of details substances into and out that the cell. Also, prokaryotes cells have actually ribosomes since they must likewise do translation, the action of translating RNA to protein in the cytoplasm. The cytosol is the area inside the cell membrane that the cell. The Golgi apparatus is membrane-bound and is for this reason only found in eukaryotic cells.

Example concern #29 : Cell frameworks


Which the the adhering to is not a eukaryote?


Possible Answers:

Protists


Archaea


Animals


Plants


Fungi


Correct answer:

Archaea


Explanation:

Remember that even fungi have well-seen nuclei and also that the presence of a nucleus is what provides a eukaryotic bio a eukaryote. Archaea are their very own domain and they room as tiny as bacteria and other prokaryotes however are fairly different. Lock live in excessive environments and also often we cannot research them because of that yet we have actually studied some such together the halophiles (salt-loving archaea).

Example question #30 : Cell structures


Which that the complying with cellular frameworks are usual to both prokaryotes and also eukaryotes?


Possible Answers:

golgi bodies


chloroplasts


nucleoli


ribosomes


mitochondria


Correct answer:

ribosomes


Explanation:

Ribosomes are materials of prokaryotes and also eukaryotes. Prokaryotes, although lock came prior to eukaryotes, absence nucleoli, chloroplasts, mitochondria, and also Golgi bodies. Ribosomes makes proteins and also eukaryotes and also prokaryotes both require proteins come function.
