Final answer:
Ribosomes play a crucial role in protein synthesis in both animal and plant cells through the process of translation.
Step-by-step explanation:
Ribosomes are responsible for synthesizing proteins in both animal and plant cells. They are small, spherical structures composed of RNA and protein. Ribosomes read the genetic code from the messenger RNA (mRNA) and assemble amino acids into a polypeptide chain, which folds into a functional protein. This process, called translation, occurs in the cytoplasm of the cell.
