Identify an option that does NOT represent prokaryotic cells.
Question

Identify an option that does NOT represent prokaryotic cells.

A.

Mycoplasma

B.

Blue-green alga

C.

Sperm

D.

Pleuropneumonia-like organism

Correct option is C

The correct answer is (c) Sperm.

Sperm cells are not prokaryotic cells; they are eukaryotic cells, which are found in multicellular organisms like humans. Eukaryotic cells have a well-defined nucleus and membrane-bound organelles, whereas prokaryotic cells (like Mycoplasma and blue-green algae) lack a true nucleus and membrane-bound organelles.

Information Booster:

  • Prokaryotic cells: These are simple, single-celled organisms without a membrane-bound nucleus. Examples include bacteria, Mycoplasma, blue-green algae (cyanobacteria), and pleuropneumonia-like organisms.
  • Eukaryotic cells: These cells have a well-defined nucleus and various organelles enclosed within membranes. Sperm cells are eukaryotic as they belong to multicellular organisms and contain a nucleus and other organelles.
  • Sperm cells: A part of the male reproductive system in animals, sperm cells are highly specialized and have a distinct nucleus and other structures, making them eukaryotic.
