The nucleolus is a prominent substructure within the nucleus of a plant cell, primarily responsible for the production and assembly of ribosomal RNA (rRNA) and ribosome subunits. It synthesizes rRNA molecules, which are essential for ribosome formation, and combines them with proteins to create the ribosomal subunits. These subunits are then transported to the cytoplasm, where they play a crucial role in protein synthesis. Additionally, the nucleolus is involved in regulating the cell cycle and responding to cellular stress.
