The rER (rough endoplasmic reticulum) and the ribosomes.

Explanation:

The rER consists of flattened membrance sacs and has ribosomes attached to it. There are also ribosomes moving freely in the cytoplasm. The proteins synthesised in the rER are secreted from the cell, while the proteins synthesised inside the cell at the ribosomes that are moving freely in the cytoplasm, remains within the cell.
