. A nuclear envelope is a derivative of
B: Rough endoplasmic reticulum
C: Smooth endoplasmic reticulum
D: Membrane of Golgi complex
The nuclear envelope is also known as karyotheca, nucleolemma.
The nucleus membrane is a lipid bilayer, inner nuclear envelope, and outer nuclear envelope, with perinuclear space between the two membranes.
The perinuclear space and outer nuclear membrane are continued with the endoplasmic membrane.
The nuclear envelope has small pores for in and out movement of the substances.
Rough endoplasmic reticulum derives nuclear envelope during telophase.
So, The correct option is B (Rough-endoplasmic reticulum).
