Why is endoplasmic reticulum absent in prokaryotes?
in the prokaryotes the nuclear region is not fully developed or it is not bounded by the membrane so nucleoplasm has direct contact with the cytoplasm of the cell..
Why ER is present in all eukaryotic cells?
endoplasmic reticulum (ER), in biology, a continuous membrane system that forms a series of flattened sacs within the cytoplasm of eukaryotic cells and serves multiple functions, being important particularly in the synthesis, folding, modification, and transport of proteins .
Can ER be found in prokaryotic cells?
Prokaryotic cells contain a single compartment enclosed within the cell membrane. Prokaryotes lack a defined nucleus (which is where DNA and RNA are stored in eukaryotic cells), mitochondria, ER, golgi apparatus, and so on. In addition to the lack of organelles, prokaryotic cells also lack a cytoskeleton.
What is present in a eukaryotic cell but not in a prokaryotic cell?
Eukaryotic cells contain membrane-bound organelles, such as the nucleus, while prokaryotic cells do not. Differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts, the cell wall, and the structure of chromosomal DNA.
Why is it important to know the difference between prokaryotes and eukaryotes?
It is important to know the differences between prokaryotic and eukaryotic cells; allows us to control disease-causing bacteria without harming our own cells.
Which process does not occur in prokaryotes?
Prokaryotes do not have membrane-enclosed nuclei. Therefore, the processes of transcription, translation, and mRNA degradation can all occur simultaneously.
Which organelle is found in all eukaryotic cells but not in prokaryotic cells?
Explanation: Prokaryotic cells do not have membrane-bound organelles or nuclei. However, they do have ribosomes. On the other hand, centrioles, the endoplasmic reticulum, the mitochondria, and the nucleus can all be found in eukaryotic cells, but not prokaryotic cells.
Does eukaryotes have endoplasmic reticulum?
In addition to the nucleus, eukaryotic cells may contain several other types of organelles, which may include mitochondria, chloroplasts, the endoplasmic reticulum, the Golgi apparatus, and lysosomes. Each of these organelles performs a specific function critical to the cell’s survival.
What is the difference between eukaryotic cell and prokaryotic cell?
The primary distinction between these two types of organisms is that eukaryotic cells have a membrane-bound nucleus and prokaryotic cells do not. The nucleus is where eukaryotes store their genetic information.
