Question

Are mesosomes present in both prokaryotic and eukaryotic cells?

Answer 1

Cell organelles as we know are the components of a cell. They are useful for performing different activities of the cell just like the organ system in the body. Cells perform different activities like- cell repair, blood formation, repair damaged tissues etc. Cells are the vital structures of life. As we knew, cell types are of $2$ types- animal cell and plant cell.

Complete answer:
nucleolus is the large structure which is present inside the nucleus. It helps in ribosome biogenesis. It is the major organelle in eukaryotic cells. Plastids are usually significant in prokaryotic cells but they are also found in plants, algae and smaller eukaryotes too.
Ribosomes are structures which are composed of proteins and they are not covered up by any membrane. Ribosome’s main function include protein synthesis as proteins or polypeptides are formed from the surface of ribosomal membrane. Hence, they are called the protein factory of the cell engine.
mesosomes are inner folding for plasma membranes. Mesosomes have functions like to provide good structure to the plasma membrane. Usually, they are found in prokaryotic cells but also, they can be seen in eukaryotic cells. Hence, mesosomes are present in both the cells. Apart from providing good posture to cells they also contribute in respiration of cell and DNA formation.

Note:
Eukaryotic and prokaryotic organelles are $80$s and $70$s. ribosomes are the major site for the polypeptide synthesis. Hence, polypeptides are the building blocks of our body. And as cells are multicellular structures. So, it helps in all vital components in our bodies. Apart from ribosomes, plastid major organs like- mitochondria, Golgi apparatus, and chloroplast reside in both the cells.
