well I can tell you where they are located if that helps. the cytoplasm, the surface of the endoplasmic reticulum, the mitochondria, and on chloroplasts.
no they are not surrounded by any membrane
The smooth endoplasmic reticulum is surrounded by a single membrane. It lacks ribosomes on its surface unlike the rough endoplasmic reticulum.
ribosomes
The rough endoplasmic reticulum is characterized by ribosomes on the surface. When viewed (using an electron microscope) they appear as black dots. Ribosomes are responsible for translating mRNA into protein and use tRNA to obtain the amino acids needed for the process. Ribosomes are actually composed of two subunits (30S and 50S in humans).
Prokaryotic ribosomes are smaller (70S) compared to eukaryotic ribosomes (80S). Prokaryotic ribosomes consist of a 30S and a 50S subunit, while eukaryotic ribosomes consist of a 40S and a 60S subunit. Prokaryotic ribosomes have fewer proteins compared to eukaryotic ribosomes.

ribosomes are a mysterious mixture of beauty and power
The ribosome is an organelle that is not surrounded by a membrane.
no they are not surrounded by any membrane
Ribosomes are the safe answer.
Ribosomes are found in both prokaryotic and eukaryotic cells and are not bound by a membrane.
Nucleus is surrounded by nuclear envelop.So they have to pass it.
They are both living organisms.They both have cell membrane. Most prokaryotes and some eukaryotes are also surrounded by the cell wall, although the makeup of the cell wall differs on the type.They both have ribosomes, although prokaryotic ribosomes are different from eukaryotic ribosomes.They both have DNA. In eukaryotes, they are surrounded by nuclear membrane. In prokaryotes, they are suspended in the nucleoid region.
The smooth endoplasmic reticulum is surrounded by a single membrane. It lacks ribosomes on its surface unlike the rough endoplasmic reticulum.
Ribosomes are mini cellular structures that are responsible for protein synthesis in cells. They help translate the genetic information from the cell's DNA into functional proteins that carry out various functions in the body.
Protein synthesis occurs at ribosomes, which can be found in the cytoplasm of a cell. In eukaryotic cells, proteins can also be synthesized on ribosomes located on the rough endoplasmic reticulum.
