Prokaryotic cells are significantly smaller than eukaryotic cells. What is its relative size?

Prokaryotic cells are significantly smaller than eukaryotic cells. What is its relative size? Correct Answer 0.1 - 5.0 μm in diameter

The correct answer is 0.1 - 5.0 μm in diameter.Key Points

  • Organisms that lack a membrane-bound nucleus are called prokaryotes.
  • A prokaryotic cell does not contain a well-defined nucleus.
  • All prokaryotes have a cell wall surrounding the cell membrane except in mycoplasma.
  • The nucleolus is absent in prokaryotic cells.
  • The fluid matrix filling the prokaryotic cell is the cytoplasm.
  • Prokaryotic cells are significantly smaller than eukaryotic cells with 0.1 - 5.0 μm in diameter.
  • Membrane-bound cell organelles are absent in prokaryotes.
  • In prokaryotes, cell division takes place by fission or budding.
  • Blue-green algae, bacteria, and mycoplasma are examples of prokaryotes.

Additional Information 

  • Organisms that have membrane-bound nuclei are called eukaryotes.
  • In eukaryotes, cell division takes place by mitosis or meiosis.
  • All living organisms are made up of cells.
  • ​Cell is the basic structure and functional unit of life.
  • The study of cells is called cytology.
  • The word 'cell' was first coined by Robert Hook in 1665.
