Eukaryotic Cell

  • The cells which contain true nuclei are called eukaryotic cells.
  • Eukaryotic cells are found in animals, plants, algae and fungi.
  • They are larger in size as compared to prokaryotic cells.
  • The cells may vary in shape, size and physiology but they all have a typical structure with little variations in number and location of cellular organelles.
  • The eukaryotic cell have a outer covering membrane called plasma membrane / cell membrane.
  • Inside the cell a membrane-bound nucleus is present.
  • Between the nucleus and plasma membrane, cytoplasm is present in which various cellular organelles like mitochondria, golgi complex, centrioles etc can be seen.
Shape:
  • Eukaryotic cells exhibit diversity.
  • They can be spherical, triangular, tubular, cuboidal, polygonal, cylindrical, oval, rounded or elongated.
  • Shape of cells may vary from organ to organ.
  • A single organ may show variations in shape of cell.
Size:
  • Eukaryotic cells are microscopic.
  • They are larger in size as compared to prokaryotic cells.
  • They size range from 0.001 mm to 175 mm.
  • Ostrich egg cell is largest cell, about 175mm in diameter.
  • Nerve cells may reach up to the length of 3 to 3.5 feet.
