Detailed explanation-1: -Answer and Explanation: Large numbers of ribosomes are present in cells that specialize in producing proteins. Ribosomes are small cellular organelles that are found in all cells. They carry out the process of protein synthesis in the cells.

Detailed explanation-2: -During protein synthesis, ribosomes assemble amino acids into proteins. Ribosomes are the cellular structures responsible for protein synthesis.

Detailed explanation-3: -The correct answer is: c) proteins Therefore, cells that specialize in producing proteins have particularly large numbers of ribosomes.

Detailed explanation-4: -The ribosome is universally responsible for synthesizing proteins by translating the genetic code transcribed in mRNA into an amino acid sequence. Ribosomes use cellular accessory proteins, soluble transfer RNAs, and metabolic energy to accomplish the initiation, elongation, and termination of peptide synthesis.

Detailed explanation-5: -Ribosomes are remarkably abundant in cells. A single actively replicating eukaryotic cell, for example, may contain as many as 10 million ribosomes. In the bacterium Escherichia coli (a prokaryote), ribosomes may number as many as 15, 000, constituting as much as one-quarter of the cell’s total mass.
