The reason details of cells can only be seen through a microscope is they are so small they can not be seen by the human eye.The diameter of a cell is 0.0076mm compared to how far an eye can see is 0.1mm so that is why the human eye cannot see something as tiny as a cell. = **__Why are cells so small?__**  = The reason cells are so small is you compare a cells growth to the volume of growth.The volume grows faster than the surface area so they are forced to be small. Plus when there small it is eaiser for them to change thier surronding enviorments. Also cells have to be fully functional to work well. If they are small they will work faster. When cells are larger than thier suppose to be they usually do not grow as they should. They also remain small so when one dies you can not feel it. If they were large you would feel it and it will take longer to grow back. Cells will die if they get to large from phenomnon. A way cells work faster is if thier small they will be more effcient at receving nutrients. Another reason cells work faster when their small is they get rid of waste through thier outer surface. = __** Fun Facts about Cells**__  = Not all cells are small an example is the yolk of an egg it is lage because it doesn't have to take in nutrientince. The first man to discover a cell under a microscope was Anton van Leeuwenhoke. There are over a billon cells in one cubic inch. There are more bacterial cells than human cells. Our bodies can contain anywhere from 75 to 100 trillion cells in our body.
