The organelle that produces proteins is the ribosome, option C. To understand why, let's discuss the function and location of each organelle mentioned.
A. Nucleus: The nucleus is the control center of the cell, which houses the genetic material (DNA). It is responsible for regulating cell activities and contains the instructions for building proteins, but it does not directly produce proteins.
B. Lysosome: Lysosomes are involved in intracellular digestion and waste removal, not protein production.
C. Ribosome: Ribosomes are tiny structures found either floating freely in the cytoplasm or attached to the endoplasmic reticulum (ER). They are considered the protein factories of the cell. Ribosomes use the instructions encoded in the DNA to synthesize proteins by assembling amino acids in a specific sequence.
D. Golgi body (also referred to as the Golgi apparatus): The Golgi body is involved in processing, modifying, and packaging proteins. It is responsible for sorting and sending proteins to their correct destinations within the cell or for secretion outside the cell.
In summary, the ribosome is responsible for the actual production (translation) of proteins, based on the instructions stored in the DNA.
