Which cell organelle is present in both prokaryotic and eukaryotic cells?
Which of the following is a prokaryote?
Prokaryotic cells are cells that do not have a true nucleus or most other cell organelles. Organisms that have prokaryotic cells are unicellular and called prokaryotes. Bacteria and archaea are prokaryotes.

Nuclear membrane is absent in:
Nostoc is a prokaryote. Prokaryotic cells lack membrane bound organelles and well organized nucleus, that is nuclear envelope is absent in these cells.
The prokaryotic cells are characterised by:
Most prokaryotes carry a small amount of genetic material in the form of a single molecule, or chromosome, of circular DNA. The DNA in prokaryotes is contained in a central area of the cell called the nucleoid, which is not surrounded by a nuclear membrane.
Eukaryotic cells are different from prokaryotic cells in having:
The distinction is that eukaryotic cells have a "true" nucleus containing their DNA, whereas prokaryotic cells do not have a nucleus.
Protoplasm found inside the nucleus is known as
Similar to the cytoplasm of a cell (protoplasm), the nucleus contains 'nucleoplasm' (nucleus sap) or karyoplasm. The nucleoplasm is one of the types of protoplasm, and it is enveloped by the nuclear membrane or nuclear envelope. The nucleoplasm includes the chromosomes and nucleoli.
Organisms which lack mitosis division and use binary fission method for cell division are known as
The largest subunit of prokaryotic ribosomes is:
50S, roughly equivalent to the 60S ribosomal subunit in eukaryotic cells, is the larger subunit of the 70S ribosome of prokaryotes. The 50S subunit is primarily composed of proteins but also contains single-stranded RNA known as ribosomal RNA (rRNA).
In eubacteria, a cellular component which resembles a eukaryotic cell is
The plasma membrane of eubacteria resembles that of the eukaryotic cell. It is made of phospholipid, protein and some amount of polysaccharides. However, it lacks sterol, the characteristic of the eukaryotic cell membrane. Instead, there is sterol like hopanoid.
Glycocalyx is associated with ___________

So, the correct answer is 'Plasma membrane'.
