Eukaryotic Cell Definition

• Eukaryotic cells are cells that contain a nucleus and organelles, and are enclosed by a plasma membrane.
• Organisms that have eukaryotic cells include protozoa, fungi, plants and animals.
• These organisms are grouped into the biological domain Eukaryota.
• Eukaryotic cells are larger and more complex than prokaryotic cells, which are found in Archaea and Bacteria, the other two domains of life.

Characteristics of Eukaryotic Cells

• Eukaryotic cells contain a variety of structures called organelles, which perform various functions within the cell.
• Examples of organelles are ribosomes, which make proteins, the endoplasmic reticulum, which sorts and packages the proteins, and mitochondria, which produce the energy molecule adenosine triphosphate (ATP).
• They also have a true nucleus, which contains the genetic material DNA and is surrounded by a nuclear envelope.
• All of the organelles are stabilized and given physical support through the cytoskeleton, which is also involved in sending signals from one part of the cell to the other.
• In eukaryotic cells, the cytoskeleton is composed mainly of three types of filaments: microtubules, microfilaments, and intermediate filaments.
• The gel-like substance that surrounds all the organelles in the cell is called cytosol.
