Although there are differences among eukaryotes (creature that range from amoebae to elephant) overall, eukaryotic cells share many characteristics. 
Here's a breakdown:


Article Summary: Animals, plants, fungi, protists, algae, and water & slime molds are eukaryotes,  organisms composed of one or more nucleated cells. Here are the basics.

Endomembrane System of a Eukaryotic Cell, Mariana Ruiz
  • Cilia & Flagella: These extensions of the cell are covered with plasma membrane and supported internally with a structural system of microtubules—kind of like a bone covered in skin. Flagella, which are longer, and cilia, which are shorter, aid in cell movement. Cilia, which are able to beat together in a coordinated manner, can also help direct materials around the outside of the cell.

Cell Wall: The cells of plants, algae and fungi have thick, protective cell walls, which provide support, help maintain the shape of the cell, and prevent the cell from taking in too much fresh water and bursting.

  • Plasma Membrane: All cells, both prokaryotic and eukaryotic, have a plasma membrane, made mainly of phospholipids and proteins, which functions as a barrier, regulating the movement of materials between the inside and the outside of the cell.
