Cells are a feature shared by all organisms.  A cell is the basic unit of structure and function of life. 
There are many different kinds of cells.  Cells that have membrane-bound structures are called 
eukaryotic cells and cells that do not have membrane-bound structures are called prokaryotic cells.  
All organisms except bacteria are made up of eukaryotic cells.
 
Many organisms, including bacteria are unicellular, or made of only one cell.  This single cell carries 
out all the activities that keep the organism alive and allow it to reproduce.  Organisms such as 
earthworms, trees, mushrooms, and humans are multicellular, or made of many cells.  These cells 
work together to keep the organism alive and help it reproduce.  Many cells in multicellular 
organisms are specialized to do only certain jobs.  Each specialized cell in a multicellular organism 
works with other similar cells to carry out a specific job.
 
Cells come in all sizes and shapes, but most are microscopic.
