What is the name of the membrane that protects the nucleus?

• A. Cytoplasmic Membrane
• B. Nuclear Membrane
• C. Endoplasmic Reticulum
• D. Cell Membrane

Answer: (B)

The membrane that protects the nucleus is called the nuclear membrane, also known as the nuclear envelope. This structure serves to separate the contents of the nucleus from the cytoplasm of the cell, thereby helping to maintain a distinct environment for the genetic material housed within the nucleus. The nuclear membrane consists of two lipid bilayers, which create a barrier that regulates the passage of ions, molecules, and RNA between the nucleus and the cytoplasm. This selective permeability is crucial for controlling gene expression and the overall regulation of cellular activities. The other options provided do not serve this protective function for the nucleus. The cytoplasmic membrane, for instance, surrounds the entire cell and does not specifically safeguard the nucleus. The endoplasmic reticulum is involved in protein and lipid synthesis, while the cell membrane refers to the outer boundary that regulates the entry and exit of substances in the whole cell, not just the nuclear environment. Thus, the nuclear membrane is uniquely specialized for its role as a protector of the nucleus.
