A)Ribosome exist as free structures that float throughout the cytoplasm of the cell. they do not have membranes, which allows them to pick up translational RNA released from the nucleus and grab onto free amino acids in order to produce protein chains

Yes because it is a single celled organism and if it's cell would have membrane it would not be possible for it to take in nitrogen and to convert it into a consumable nitrogen because nitrogen can't pass through membrane

Ribosomes are part of cell, they are sticked on the surface of endoplasmic reticulum. ribosomes help endoplasmic reticulum in process of protein synthesis

Ribosomes lack the unit membrane . They are present individually in the cell cytoplasm and make the lining of the rough endoplasmic reticulum. Nucleolus lacks a unit membrane.They have genetic materials in the nucleus which consists of RAN, DNA, proteins etc.

Ribosomes lack membranes as they help in protein synthesis . As proteins are needed by all the different parts of the cell , they move freely across the cell

Ribosome is small granules produce through nucleolus and it is attached to the RER that's why it is not having membrane.

Ribosome do not have membrane so it is able to pick up the translational RNA released from nucleus to form proteins

Ribosomes are commonly known as the protein factories of cells and they lack membraneous covering. The ribosomes consist of two subunits; larger subunit and smaller subunit. These subunits join together only at the time of protein synthesis and are composed of ribonucleo proteins(RNP's). Since, ribosomes represent temporary association of two subunits at the time of translation(protein synthesis), they lack membraneous covering.

In cells, thesestructures are referred to as organelles. ... Non-membrane boundorganelles are more solid structures that are not fluid-filled, so they have no need for amembrane. Examples of non-membrane bound organelles are ribosomes, the cell wall, and the cytoskeleton.

As we know what are organelles and even we know that what are different kind of organelles. In the question the only ribosome is the organelle and other are present in cytoplasm and ribosome is the organelle of plant. So the answer is A.

They do not have membrane because this allows them to pick up translational RNA released from the nucleus and grab onto free amino acid in order to make protein chains.

Ribosome is present in the cell in front of rough endoplasmic reticulam. Its work is synthesis the protein . It doesnt contain any membrane so, option A is correct.

A) Ribosome is the correct answer because it is present in prokaryotic as well as eukaryotic cells. prokaryotes don't have membrane-bound organelles .Other three are only present in eukaryotic cells and are membrane bound. Therefore answer a) Ribosome is correct.

Ribosomes are comprised of RNA and protiens so because of its protien content I don't think it needs membranes and also as it has to synthesise the protiens

Ribosomes synthesis proteins which are very much important in all living organisms either in prokaryotic or in eukaryotic and as we know prokaryotic cell doesn't have membrane bound organelles so in the start of evolution ribosomes were present in prokaryotic and as they came into eukaryotic but in eukaryotic cell it will not resist without membrane and it get place on the surface of endoplasmic reticulum and didn't evlove so it remains as.
