The shape and size of a cell is related to its ____________.

Reason: Cells vary in shape and size. The smallest cell, a type of bacterium known as Mycoplasma, measures 0.0001 mm in diameter. Amongst the largest cells are nerve cells. These cells can exceed 3 m in length. Along with the differences in size, cells are present in different shapes. In humans outermost skin cells are flat while nerve cells are elongated. In multicellular organisms shape and size of the cell is mainly dependent on its job or functions.For example - flat skin cells pack tightly into a layer that protects the underlying tissue from invasion by bacteria. The numerous extensions from a nerve cell enable it to connect to several other nerve cells in order to send and receive messages rapidly.
