Definitions:

Nucleolus

The nucleolus is a small, dense region within most nuclei of eukaryotic cells, primarily involved in the assembly of ribosomes through the processing and modification of RNA.

Cell Plate

A structure that forms in plant cells during cytokinesis, dividing the cell into two separate cells.

Cell Wall

The cell wall is a rigid layer that lies outside the plasma membrane of the cells of plants, fungi, and bacteria, providing strength and protection against mechanical stress and osmotic pressure.

Plasma Membrane

The membrane found at the boundary of cells, responsible for controlling the passage of substances in and out of the cell.
