Which of the following are sometimes attached to the endoplasmic reticulum?

Understand the Problem

The question appears to be a multiple-choice quiz related to biology, specifically focusing on cell biology and genetics concepts. Each question asks for information on various topics such as cellular structures, reproductive processes, and the classifications of organisms.

More Information

Ribosomes are responsible for protein synthesis and attach to the rough endoplasmic reticulum to synthesize proteins for export from the cell.

Tips

A common mistake is confusing the rough and smooth ER; only the rough ER has ribosomes attached.
