ribosomes
In cytoplasm,On Rough ER,in mitochondria and chloroplasts
They synthesize proteins needed.In eukariyotes they are on ER and in cytoplasm.
The endoplasmic reticulum (ER) is located throughout the cell, with two main regions: the rough ER, which is studded with ribosomes and involved in protein synthesis, and the smooth ER, which is important for lipid synthesis and detoxification. The ER is a network of membranes that extends from the nucleus to the cell membrane in eukaryotic cells.
The endoplasmic reticulum is a network of interconnected membranes inside the cytoplasm. It originates in (or is connected to) the nuclear envelope.
Proteins are made in the ER and golgi, not the cytoplasm.

The endoplasmic reticulum (ER) is an organelle found in eukaryotic cells. It is located throughout the cytoplasm and can be classified into rough ER, which is studded with ribosomes, and smooth ER, which lacks ribosomes.
The endoplasmic reticulum (ER) is the organelle in animal cells that has a netlike structure in the cytoplasm. There are two types of ER – smooth ER involved in lipid metabolism and rough ER studded with ribosomes involved in protein synthesis.
Rough endoplasmic reticulum is found throughout the cytoplasm of the cell, often located adjacent to the cell nucleus. It appears rough due to the presence of ribosomes on its surface, which are involved in protein synthesis. Rough ER plays a key role in protein production and transport within the cell.
