👉 Mnioes are a group of small, interconnected structures that make up the cell membrane in eukaryotic cells. They contain proteins and nucleic acids that regulate the flow of substances between the cell and its surrounding environment. Mnioes also play an essential role in the process of energy production within the cell by serving as a conduit for the diffusion of nutrients and waste products to and from the cytoplasm, which is where most of the cell's metabolic activity occurs.
