Larger and more numerous nucleoli are typically present in cells that are actively carrying out:

Step-by-step solution

The nucleolus is a non-membrane bound structure in the nucleoplasm and is the principal site for the synthesis of ribosomal RNA (rRNA). Ribosomes are the cellular organelles responsible for protein synthesis. Cells that are actively engaged in protein synthesis require a large number of ribosomes to meet their metabolic demands. Consequently, such cells possess larger and more numerous nucleoli to facilitate the rapid production of rRNA and assembly of ribosomal subunits. Answer: Protein synthesis
