Question

Briefly explain why prokaryotic and eukaryotic cells are different. Include the description of what the difference is in each cell type.

Answer 1

Ans) As Per Cell Theory :

As per cell theory , all living cell is made up of cell i.e. cell is the basic unit of life.

All living cells are classified as Prokaryotes and Eukaryotes. Except bacteria, all other life form i.e. plants , animals and humans are Eukaryotes. As compared to Eukaryotes , Prokaryotic cells are much simple in nature because they are small in size and hence , has large surface to volume ratio. It means that they can easily transport nutrients to the other parts of cell whereas , in Eukaryotes , surface to Volume ratio is small which means that there is slow diffusion of nutrients to interior of cell and hence , needs different specialized organelles to carry out the function like metabolism , transportation of chemical , etc.

1. Nuclear Body : Nuclear Body is enclosed by the nucleus membrane in Eukaryotes whereas , nuclear membrane is absent in prokaryotes.

2. In Eukaryotes , Nucleolus is present but is absent in Prokaryotic cell.

3. The cell of Eukaryotes is divided by the process of Mitosis but Prokaryotic cell divides by binary fission.

4. ETS is present in Mitochondria in Eukaryotes whereas , in Prokaryotes it takes place in cytoplasm.
