1 The lipid bilayer is semi-permeable, allowing only certain molecules to diffuse across the membrane. 2  Cholesterol is another lipid component of animal cell membranes.t also serves as a base of attachment for the cytoskeleton in some organisms and the cell wall in others. Thus the cell membrane also serves to help support the cell and help maintain its shape. Animal cells, plant cells, prokaryotic cells, and fungal cells have cell membranes.
The higher the frequency, the shorter (lower) the wavelength. Energy is proportional to frequency, and higher frequency wa â¦ ves will have a higher energy.   Mathematically, frequency = 1 divided by wavelength, or f = 1/Î»   Use the link below for more information, including a diagram or two to make things clearer.requency is inversely proportional to wavelength (higher frequency means a shorter wavelength). Frequency is directly proportional to the energy of the wave (higher frequenc â¦ ies correspond to higher energies). 2 people found this useful.
The relationship between the energy of an electromagnetic wave and its frequency is expressed by the equation: E = hn = hc/l where E is the energy in kilojoules per mole, h is Planck's constant, and the other variables are defined as discussed previously.
