Answer:
Ribosomes are the organelles that help in protein synthesis. Protein is required for many cell activities such as damage repair and other chemical processes.
Explanation:
The important ribosome function includes:
- It assembles amino acid to form proteins that are essential to carry out cellular functions.
- The DNA produces mRNA by the process of DNA transcription.
- The mRNA is synthesized in the nucleus and transported to the cytoplasm for the process of protein synthesis.
- The ribosomal subunits in the cytoplasm are bound around mRNA polymers. The tRNA then synthesizes proteins.
- The proteins synthesized in the cytoplasm are utilized in the cytoplasm itself, the proteins synthesized by bound ribosomes are transported outside the cell.

Answer:
- A ribosome is a complex molecular machine found inside the living cells that produce proteins from amino acids during the process called protein synthesis or translation.
- The process of protein synthesis is a primary function, which is performed by all living cells.
- Ribosomes are specialized cell organelles and found in both prokaryotic and eukaryotic cells.
- Every living cell requires ribosomes for the production of proteins.

The Ribosome Structure includes the following
- It is located in two areas of cytoplasm.
- Scattered in the cytoplasm.
- Prokaryotes have 70S ribosomes while eukaryotes have 80S ribosomes.
- Around 62% of ribosomes are comprised of RNA, while the rest is proteins.
- The structure of free and bound ribosomes is similar and is associated with protein synthesis.
