Nuclear membrane is absent in organisms that fall under kingdom ______.

Monera

The correct answer is Option (3) -Monera

Nuclear membrane is absent in organisms that fall under kingdom Monera.

Monera is a kingdom that includes unicellular organisms like bacteria and archaea. These organisms are prokaryotic, meaning they lack a true nucleus enclosed within a membrane. Instead, their genetic material, usually a single circular chromosome, is located in the cytoplasm in a region called the nucleoid. Unlike eukaryotic cells found in kingdoms such as Animalia, Plantae, and Fungi, which have a distinct nucleus surrounded by a nuclear membrane, prokaryotic cells in the kingdom Monera do not possess this feature. Therefore, the absence of a nuclear membrane is a characteristic of organisms classified within the kingdom Monera.
