Answer 2

Membrane is absent in Ribosomes.

So, the correct choice to this question is Option (b)

Explaination:

• Ribosomes are the cell organelles which are found in both the types of organims, that is, in prokaryotes as well as in eukaryotic individuals.

• This cell organelle does not have any type of membrane surrounding it.

• This can be found inside the cytosol and also remains scattered in the cytoplasm. We can also find it on rough type of endoplasmic reticulum.

• In the prokaryotic individuals, 70S kind of ribosomes are found and 80S type is found in the eukaryotes.

• This organelle has a very important function in synthesising proteins.
