Yes-both plant and animal cells have a membrane-bound nucleus and organelles. The nuclear membrane controls the movement of molecules in and out of the nucleus.This is impo â¦ rtant for regulation and protection.onfidence votes 79. Nuclear membrane acts as a physical barrier, separating the nucleoplasm from the cytoplasm. It is a semipermeable membrane and allows transport of substances in and out of nucleus. Its inner membrane is involved in protein synthesis.
In eukaryote cells the nucleus is surrounded by a double membrane called the nuclear envelope. This separates the genetic material from the rest of the cell. The nuclear envelope has a large number of holes or âporesâ that allow the cell to move molecules across the nuclear envelope and in and out of the nucleus.
