Ribosome
Different proteins are produced on free-floating ribosomes than on ones attached to the rough endoplasmic reticulum (ER). In a general sense, proteins that will be used at the ER will be produced on attached ribosomes. Proteins that are meant for secretion will be made on free-floating ribosomes.
Tiny organelles that manufacture proteins for the cell are called ribosomes. They can be found either floating freely in the cytoplasm or attached to the endoplasmic reticulum, forming rough ER. Ribosomes translate messenger RNA (mRNA) into amino acid sequences, creating proteins that serve various functions, including structural roles like hair or functional roles such as enzymes.
The rough ER had ribosomes attached while the smooth ER had no ribosome attached.
No, they do not. Prokaryotic cells have no membrane-bound organelles such as rough endoplasmic reticulum. The 70s ribosomes found in prokaryotic cells are therefore free in the cytoplasm as opposed to attached to the rough endoplasmic reticulum.

A ribosome. Ribosomes are the small spherical organelles attached to the Endoplasmic Reticulum. They produce proteins and code tRNA

Well... the cell! Most organelles (Mitochondria, some ribosomes, lysosomes, chloroplasts, centrosomes, golgi apparatus) appear to float freely in the cytoplasm (although on a more advanced level the are attached to the cytoskeleton), whereas others are attached to each other - for example the rough ER had hundreds of ribosomes attached to it, and is itself attached to the nuclear envelope!
The rough ER had ribosomes attached while the smooth ER had no ribosome attached.
organelles are the answer
No, they do not. Prokaryotic cells have no membrane-bound organelles such as rough endoplasmic reticulum. The 70s ribosomes found in prokaryotic cells are therefore free in the cytoplasm as opposed to attached to the rough endoplasmic reticulum.
transport material out of the cell
It depends if the cell in question is a prokaryotic or eukaryotic cell. In prokaryotic cells, the ribosomes are free in the cytoplasm as there are no membrane-bound organelles. In eukaryotic cells, the ribosomes are attached to the rough endoplasmic reticulum.
