EXAMPLE: 
1.the smallest measured around is 0.1 to 0.5 um or micrometer which is a bacteria cell
2.the largest cell measured around is 170 X 150 um which is a ostrich's egg.

By these examples you will be now able to say that there are different cell ranges of different cells.

NOTE: a egg is only a single cell)

THIS IS TRUE , FOR EXAMPLE THE MUSCLE CELL IS SPINDLE SHAPED AND THAT ALLOWS IT TO CONTRACT AND RELAX. IN THE SAME MANNER THE SPERM CELL HAS A TAIL WHICH HELPS IT TO MOVE TOWARDS THE OVARY. AND THE RBCs ARE ALSO BICONCAVE SHAPED WHICH HELPS IT TO CUT THROUGH THE FLUID MATTER OF THE BLOOD.
