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.
nuclear membrane. The nuclear membrane encloses the nucleus in eukaryotes. The membrane is penetrated by nuclear pore complexes. The nuclear membrane (nuclear envelope, nucleolemma) isolates the interior of the nucleus from the cytoplasm.The membrane has two layers enclosing a distinct inner lumen (em).he membrane is penetrated by nuclear pore complexes.
