The endoplasmic reticulum is continuous with the nuclear envelope. Some endoplasmic reticulum have granules called ribosomes on their surfaces and are referred to as rough endoplasmic reticulum.
The others are not associated with ribosomes and are thus referred to as smooth endoplasmic reticulum. The rough endoplasmic reticulum transports proteins while the smooth endoplasmic reticulum synthesizes and transport lipids.
The nuclear envelope(membrane) encloses the nucleus and regulates the cell activity. The endoplasmic reticulum ensures growth continuity of the nucleus envelope even after damage.
The membranes of the endoplasmic reticulum are continuous with the membranes of the <u>nuclear envelope</u>.
Explanation:
The nuclear envelope of a eukaryotic cell, also called <em>nuclear membrane</em>, divides or separates the nucleus from the cytoplasm. It consists of an inner membrane and an outer membrane that <u>helps the nucleus to maintain the all its contents inside, such as the DNA, while also providing protection by preventing other substances from entering.</u>
The membranes of the nuclear envelope are continuous with the membranes of the rough endoplasmic reticulum. According to researchers, <u>the nuclear envelope and the endoplasmic reticulum are in a state of equilibrium</u>. For instance, when damage to the membrane of the nuclear envelope occurs, the endoplasmic reticulum can develop additional membrane continuities to support it.
