Ribosomes.
Ribosomes are non-membranous cell organelles responsible for protein synthesis in the cell.
Ribosomes can be thought of as assembly lines in a factory, where they read instructions (mRNA) to build proteins in a specific order. Another analogy is thinking of ribosomes as chefs in a kitchen following a recipe (mRNA) to make a dish (protein).

No, ribosomes are not always found in the endoplasmic reticulum. Ribosomes can be free-floating in the cytoplasm or attached to the endoplasmic reticulum. Ribosomes attached to the endoplasmic reticulum are called rough endoplasmic reticulum, while ribosomes in the cytoplasm are called free ribosomes.
No.
Because there are no ribosomes on the surface of this organelle, unlike its couterpart, the rough endoplasmic reticulum whcih gets its name from the presence of the ribosomes.
