What organelles is composed of two subunits and may be free in the cytosol or attached to rough ER?
Ribosome
How does the function of free ribosomes differ from the function of ribosomes attached to other organelles?
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.
How can you tell from a rough from smooth ER?
The rough ER had ribosomes attached while the smooth ER had no ribosome attached.
What are tiny cell structures that carry out specific functions within the cell called?
Organelles
What do ER organelles do?
transport material out of the cell

Ribosome
What is a small sphere attached to the Endoplasmic Reticulum aka 'ER'?
A ribosome. Ribosomes are the small spherical organelles attached to the Endoplasmic Reticulum. They produce proteins and code tRNA
What types of cells contain the organelles smooth ER and Rough ER in?
what cells have Rough ER and smooth ER
What contains all the cell organelles?
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!
Suspended in the cell's cytosol are tiny?
organelles :)

Do prokaryotes have rough er?
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.
The term means tiny?
