Verified step by step guidance

Understand the function of ribosomes: Ribosomes are the cellular structures responsible for protein synthesis. They translate messenger RNA (mRNA) into polypeptide chains, which then fold into functional proteins.

Identify the locations of ribosomes: In both animal and plant cells, ribosomes can be found in two main locations: attached to the endoplasmic reticulum (ER) and freely floating in the cytoplasm.

Differentiate between rough and smooth ER: The rough endoplasmic reticulum is studded with ribosomes, giving it a 'rough' appearance, and is involved in the synthesis of proteins destined for secretion or for use in the cell membrane. The smooth ER lacks ribosomes and is involved in lipid synthesis and detoxification processes.

Clarify the incorrect options: Ribosomes are not located inside the nucleus, within the Golgi apparatus, or embedded in the cell membrane. The nucleus contains the genetic material and is the site of transcription, while the Golgi apparatus is involved in modifying, sorting, and packaging proteins and lipids for secretion or use within the cell.

Summarize the correct locations: Ribosomes are primarily found attached to the rough endoplasmic reticulum and freely in the cytoplasm, where they play a crucial role in protein synthesis.
