Why Endoplasmic reticulum is present in eukaryotic cells but not in prokaryotic cell?
The endoplasmic reticulum (ER) is present in eukaryotic cells because it plays a crucial role in the synthesis, folding, modification, and transport of proteins and lipids, functions that are more complex in these cells. Eukaryotic cells have compartmentalized organelles, allowing for specialized processes to occur in distinct environments, which is essential for their larger and more complex structure. In contrast, prokaryotic cells lack membrane-bound organelles and have a simpler cellular organization, performing all their metabolic functions within the cytoplasm, where such compartmentalization is unnecessary. Thus, the evolutionary complexity of eukaryotes necessitated the development of structures like the ER.
What else can I help you with?
Is the smooth er in eukaryotic cell or prokaryotic?
Smooth endoplasmic reticulum (ER) is found in eukaryotic cells. It is responsible for lipid synthesis, detoxification of drugs and toxins, and storage of calcium ions. Prokaryotic cells lack membrane-bound organelles like the ER.
Do prokaryotes have rough er?
No, they do not. Prokaryotic cells have no membrane-bound organelles such as rough endoplasmic reticulum. The 70s ribosomes found in prokaryotic cells are therefore free in the cytoplasm as opposed to attached to the rough endoplasmic reticulum.
What is present only in eukaryotic cells?
Mitochondria, endoplasmic reticulum, and nucleus are all organelles that are present only in eukaryotic cells.
Do only plant cells have endoplasmic reteculum?
no endoplasmic reticulums are found in both animal and plant cells
Why endopladmic reticulum is present in all eukaryotic cells but not in prokaryotic cells?
The endoplasmic reticulum (ER) is present in all eukaryotic cells because it plays a crucial role in the synthesis, folding, and transport of proteins and lipids, which are essential for complex cellular functions. Eukaryotic cells have compartmentalized structures, allowing for specialized functions in different organelles, such as the ER. Prokaryotic cells, on the other hand, lack membrane-bound organelles and have a simpler structure, relying on different mechanisms for protein synthesis and cellular processes, making the ER unnecessary.

What type of cells have ribisomes?
Ribosomes are found in prokaryotic and eukaryotic cells. They are present in mitochondria, chloroplasts and bacteria. The ribosomes found in prokaryotes are smaller in size and are found floating in the cytoplasm of the cell. In eukaryotes ribosomes are associated with the endoplasmic reticulum to form the rough endoplasmic reticulum.
What is present only in eukaryotic cells?
Mitochondria, endoplasmic reticulum, and nucleus are all organelles that are present only in eukaryotic cells.
Do only plant cells have endoplasmic reteculum?
no endoplasmic reticulums are found in both animal and plant cells

Which organelle produces proteins in both eukaryotes and prokaryotes?
The ribosomes are the small organelles responsible for protein synthesis. They are found in both eukaryotic and prokaryotic cells, but are smaller in prokaryotic cells (70s vs 80s).
Why does a eukaryote have that a prokaryote does not?
Eukaryotes have membrane-bound organelles such as a nucleus, mitochondria, and endoplasmic reticulum that prokaryotes lack. Eukaryotic cells are typically larger and more complex in structure compared to prokaryotic cells. Additionally, eukaryotes have linear DNA organized into chromosomes, while prokaryotes have circular DNA located in the nucleoid region.
What organelles are found in prokaryotic cells eukaryotic cells plant cells and animal cells?
This may not help you much, bit eukaryotic cells are cells that do not have a nucleus.A prokaryote does not have a nucleus, nor does it have mitochondria, chloroplasts, Golgi apparatus, endoplasmic reticulum, and other organelles present in eukaryotic cells. Carboxysome structures, sometimes called polyhedral organelles because of their shape, perform metabolism functions inside the prokaryotic cell.
What are 5 differences between prokaryotics and eukaryotics?
prokaryotic:-1 True nucleus not present. 2 membrane bound organelles are lacking. 3 size- 1-10mm 4 single chromosomes. 5 nucleus absence. Eukaryotic:- 1True nucleus present. 2 organelles are membrane bounded. 3 size- 5-100mm 4 more than 1 chromosomes. 5 nucleus present.
Is the endoplasmic reticulum in a planet cell or in a animal cell?
endoplasmic reticulum is present both in plant cell and animal cell
How prokaryotic organism lack?
Prokaryotic organisms lack a membrane-bound nucleus, meaning their genetic material is not enclosed within a nuclear membrane; instead, it is located in a region called the nucleoid. They also lack membrane-bound organelles, such as mitochondria or endoplasmic reticulum, which are found in eukaryotic cells. Additionally, prokaryotes are typically unicellular and have a simpler structure compared to eukaryotes. Their cell walls, when present, are often composed of peptidoglycan, distinguishing them from eukaryotic cells.
