Nuclear membrane is absent in
Show Hint
Unicellular, prokaryotic organisms like cyanobacteria, mycoplasma are bacterial cells that are not made up of cellulose. The cell organelles and well-defined nucleus are absent in these organisms.
- Penicillium
- Agaricus
- Volvox
- Nostoc
The Correct Option is D
Solution and Explanation
The nuclear membrane is absent in Nostoc.
Penicillium and Agaricus from the options above are fungi. Volvox is an alga. All these three organisms fall into the category of eukaryotes. They all have a membrane-bound nucleus. Nostoc is a cyanobacterium from the kingdom of prokaryotes. These do not have a true nucleus and thus the nuclear membrane is absent.

Eurkaryotic Cells - Golgi Apparatus
The Golgi apparatus is also known as the Golgi complex or the Golgi body. The term is derived from Camillo Golgi, the scientist who discovered the organelle. It can be found in all eukaryotic cells, including plants and animals. They are membrane-bound organelles found in the cell's cytoplasm.
Formation of acrosome: The acrosome is a component of the tip of animal sperms that aids in the digestion of the egg or ovum covering sheath during fertilisation. The Golgi complex produces it with the help of its vesicles.
