Detailed explanation-1: -The presence of a nucleus is the principal feature that distinguishes eukaryotic from prokaryotic cells. By housing the cell’s genome, the nucleus serves both as the repository of genetic information and as the cell’s control center.

Detailed explanation-2: -The nucleus is the control center of the cell. The nucleus of living cells contains the genetic material that determines the entire structure and function of that cell.

Detailed explanation-3: -The nucleus controls and regulates the activities of the cell (e.g., growth and metabolism) and carries the genes, structures that contain the hereditary information. Nucleoli are small bodies often seen within the nucleus. The gel-like matrix in which the nuclear components are suspended is the nucleoplasm.

Detailed explanation-4: -Prokaryotic cells do not have a nucleus. All cells can are classified as prokaryotic or eukaryotic based on their internal structure. Eukaryotic cells contain a nucleus-a structure enclosed in a membrane that contains the majority of the cell’s genetic material. Prokaryotic cells lack nuclei.

Detailed explanation-5: -The cell’s entire activity is monitored by the nucleus. It serves as the control room for cell functions as well as the repository for the cell’s DNA. It stores a cell’s genetic information and regulates its growth and proliferation.
