Eukaryotic cells are significantly larger than prokaryotic cells. What is range of the size of the Eukaryotic cells?

Eukaryotic cells are significantly larger than prokaryotic cells. What is range of the size of the Eukaryotic cells? Correct Answer 10–100 µm in diameter

The correct answer is 10–100 µm in diameter.

Key Points

• Eukaryotic cells
  • Eukaryotic cells are generally bigger — up to 10 times bigger, on average than prokaryotes. 
  • The range of the size of the Eukaryotic cells is 10–100 µm in diameter.
  • The eukaryotic cells are the advanced cells that have a well-defined nucleus that is surrounded by a double-layered nuclear membrane.
  • Within the nuclear membrane, the genetic material is present on the chromosomes.
  • In eukaryotic cells, there is extensive compartmentalisation of cytoplasm through the presence of membrane-bound organelles.
  • Eukaryotic cells possess an organised nucleus with a nuclear envelope.  
  • The genetic material is double-stranded DNA that is bound with positively charged histone proteins.
  • The nucleus also has its own nucleoplasm that serves as the base for nuclear activities like DNA replication and RNA formation.  

Additional Information

• Prokaryotic cells
  • Prokaryotic cells are single-celled microorganisms known to be the earliest on earth.
  • The organisation of the prokaryotic cell is fundamentally similar even though prokaryotes exhibit a wide variety of shapes and functions.
  • All prokaryotes have a cell wall surrounding the cell membrane except in mycoplasma.
  • The fluid matrix filling the cell is the cytoplasm. There is no well-defined nucleus.
  • They are generally smaller and multiply more rapidly than the eukaryotic cell. They may vary greatly in shape and size.  
  • The prokaryotic cells are represented by bacteria, blue-green algae, mycoplasma and PPLO (Pleuro Pneumonia Like Organisms).
