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 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).
The ribosomes. There are many ribosomes within an animal cell.
Ribosomes
The cell organelles that make protein are the ribosomes. There are two types of ribosomes: free ribosomes and bound ribosomes.
rough endoplasmic reticulum
ribosomes are a mysterious mixture of beauty and power
no they are not surrounded by any membrane
Ribosomes are the safe answer.
The ribosome is an organelle that is not surrounded by a membrane.
Ribosomes aren't mini anything, really. They are made up of rRNA, are not surrounded by a membrane and their function is to assemble polypeptides (make proteins).
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.

Cells are surrounded by a barrier called a cell membrane and at some point in their lives they contain the molecule that carries biological information (DNA). The structures that all cells have are ribosomes, plasma membrane, cytoplasm, and genetic material.
