${\bf{\red{\underline{\underline{Nucleus:-}}}}}$

❇ The nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction.

❇ It is commonly the most prominent organelle in the cell.

Nucleus consist of:-

★ ${\bf{\purple{\underline{\underline{Nuclear\;membrane:-}}}}}$ The nucleus is enclosed by a double layered cellular membrane called the nuclear membrane.

★ ${\bf{\purple{\underline{\underline{Nucleoplasm:-}}}}}$ The nucleus contains a nuclear sap, enclosed by the nuclear envelope, which is known as the nucleoplasm. This holds the nucleoli and suspends the chromatin's.

★ ${\bf{\purple{\underline{\underline{Nucleolus:-}}}}}$ The nucleolus is a sub-organelle present inside the nucleus. It can be observed as dark spot under the microscope.

★ ${\bf{\purple{\underline{\underline{Nucleoli:-}}}}}$ Nucleoli are made up of proteins, ribosomal RNA (rRNA), and ribosomal DNA (rRNA).

★ ${\bf{\purple{\underline{\underline{Chromatin\;Network:-}}}}}$ DNA gets associated with protein molecule to form chromatin. Chromatins are present in the nucleoplasm.
