Which is not present in prokaryotes :-a)Ribosomeb)Mitochondriac)Cytoplasmd)MesosomeCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Mitochondria..mesosomes act as mitochondria

Answer

B) mitochondria is present in case of eukaryotic organism and not in prokaryotes

Answer

The reason is because prokaryotes lack well defined Nucleus and mesosomes act as mitochondria...M

Answer

Mitochondria  is not present in prokaryotes. Cz mesosome act as mitochondria.

Answer

Since prokaryotes represent the population of the earliest form of life, they are less advanced in organisation and in fact, don't possess membrane bound cell organelles.

Answer

Mitochondria is itself a prokaryotic cell organelle. And acc to bookish language , it is a double memb bound structure..

Answer

Mitochondria .. As it's membrane bound str..!

Answer

I dont think this is ques to ask..this is factual

Answer

Mitochondria are absent in prokaryotesProkaryotes also produce energy but they it with the help of the enzymes present on its cell's surfaceThe cellular membrane can fold itself to encourage energy production through these enzymes

Answer

Ribosome:
- Ribosomes are present in both prokaryotes and eukaryotes.
- They are responsible for protein synthesis.
- In prokaryotes, ribosomes are smaller in size (70S) compared to eukaryotes (80S), but they perform the same function.

Cytoplasm:
- Cytoplasm is present in both prokaryotes and eukaryotes.
- It is a gel-like substance that fills the cell and surrounds the organelles.
- Many cellular processes such as metabolism, protein synthesis, and cell division occur in the cytoplasm.

Mesosome:
- Mesosomes are found in prokaryotes only and are not present in eukaryotes.
- They are invaginations or extensions of the plasma membrane in prokaryotic cells.
- Mesosomes play a role in cell division, DNA replication, and respiration in prokaryotes.

Mitochondria:
- Mitochondria are membrane-bound organelles found in eukaryotic cells.
- They are known as the 'powerhouses' of the cell as they produce energy in the form of ATP through cellular respiration.
- Mitochondria have their own DNA and can replicate independently within the cell.
- They are absent in prokaryotes.

Conclusion:
The correct answer is option 'B' - Mitochondria. Prokaryotes do not have mitochondria, as these organelles are exclusive to eukaryotic cells. Prokaryotes generate energy through other means, such as glycolysis and fermentation.
