For the cell to survive, its membrane must have a viscous property. If the
cell membrane loses this, then proteins in the membrane can't fulfill their
functions and the membrane loses its permeability.
liq uids out side the cell lead to hard en ing of the cell mem -

In his book Nature's Destiny, the micro bi ol o gist
Michael Denton draws atten tion to the essen tial nature of
this struc ture of the cell mem brane:
One of the most impor tant struc tures in the cell, which is large -
ly com posed of lip ids, is the cell mem brane. It is dif fi cult to see
how a cell could sur vive with out some sort of bond ing mem -
brane which was rel a tive ly imper me a ble to the cell's con stit u -

acids—to pre vent its con tents from dif fus ing away into the sur -

the cell and its envi ron ment. . . . As one lead ing biol o gist points
