Because, if you were made up of one big cell, there would be too much surface area to total area ratio, and you would not be able to absorb the things you need to live. Also, you need different types of cells in order to function.
In other words, you need cells to be small in order to keep them alive, and you need many of them because they each have different 'jobs' in the body.
particles
The term for a placeholder made up of small boxes called cells is a grid.
No, a virus is not made up of cells. It is a small infectious agent that can only replicate inside the cells of living organisms.

Organs are made up of small cells instead of large cells to allow the organs to be not easily harmed. This way if one cell dies or is attacked then the organ will not be damaged. If the cell was larger then the organ might not be able to recover.
