Why does the nucleus have an envelope around it? What are the principal roles of nucleus?

Dear Student,

Please find below the solution of your asked query:

Reason for Nuclear envelope- Nuclear envelope or nuclear membrane provides a barrier between the nuclear content from cytoplasm of the cell. It encloses the genetic material inside the cell.

Functions/Roles of the nucleus:

• The nucleus controls all metabolic activities of a cell. 
• It is concerned with the transmission of hereditary traits from the parent to the offspring.
• It plays an important role in cellular reproduction—the process by which a single cell divides to form two new cells.
• It also plays a crucial part in determining the way a cell will develop and the form it will exhibit at maturity. It does this  by directing the chemical activities of the cell.

Hope this information clears your doubts about the topic.
