⭐Nucleus:-

The cell nucleus is a membrane-bound structure that contains a cell's hereditary information and controls its growth and reproduction. It is the command center of a eukaryotic cell and is usually the most notable cell organelle in both size and function.

⭐Nucleolus:-

The nucleolus is the largest structure in the nucleus of eukaryotic cells. It is best known as the site of ribosome biogenesis. Nucleoli also participate in the formation of signal recognition particles and play a role in the cell's response to stress.

⭐Nucleoid:-

The nucleoid is an irregularly shaped region within the cell of a prokaryote that contains all or most of the genetic material. The length of the DNA chromosome is very large compared to the dimensions of the cell, and so must be compacted to fit.
