Yes, they may not seems like an organelle such as mitochondria, but ribosomes are huge molecular structures, comprised of RNA(ribo nucleic acids) and proteins which carry out the proteins synthesis in cytoplasm.
Ribosomes
Ribosomes synthesize proteins by translating messenger RNA. They can also assemble proteins into their final three-dimensional structures. Ribosomes can modify nascent polypeptides by adding certain chemical groups. Additionally, ribosomes can help target proteins to their appropriate subcellular locations.
The eyes belong to the Nervous system.
In this context, "subcellular" refers to different compartments within a cell where proteins are directed to carry out specific functions. These compartments can include organelles such as the nucleus, mitochondria, endoplasmic reticulum, and Golgi apparatus. Proteins are directed to these subcellular destinations to perform various roles in cellular processes.
Ribosomes are found in all cells, including bacteria. Some people reserve the word "organelle" for subcellular structures that have a membrane around them, in which case bacteria contain no organelles at all. Other people are happy to call ribosomes organelles, in which case that is your answer.

In translation (RNA to Protein) a ribosome attaches to an mRNA strand and uses the mRNA to create a protein. There are other types of RNA and protein that can modify the mRNA strand but ribosomes are the main structure involved in translation.
Yes, a membrane would be a subcellular structure.
Yes, membranes are a subcellular structure found in cells. They are thin, flexible barriers made up of lipid bilayers that separate the internal environment of cells from the external environment. Membranes play crucial roles in regulating the passage of substances in and out of cells, compartmentalizing cell organelles, and facilitating cell communication.
