Purpose: to provide an accurate representation or model of the molecular structure of the cell
membrane students who are studying Biology, and to build this structure utilizing the model.
Background information: A fundamental theme in biology is the connection between structure and
function. This is true both at the molecular and cellular level. The molecule which make up the cell
membrane are phospholipid is vital in the formation of the cell membrane as the membrane as the
structure which surrounds The molecules which make up the cell membrane are phospholipids which do
not dissolve in water. The property of phospholipids is vital in the formation of the cell membrane as
the membrane is the structure which surrounds the cell. The structure of the cell membrane is a double
layer of phospholipids called a bi layer.
Each phospholipid is made up of a head and two tails. The head is polar positive while the two tails are
non-polar negative. The polar heads are attracted to water while the non-polar are repelled by water.
This is hydrophilic and hydrophobic.
Transport proteins are molecules which allow substances to move into or out of the cell which are
unable to move directly through the cell membrane.
Questions:
Create a 3 D model of a cell membrane using the materials given. Draw
what you create on a piece of paper and label the parts of the model.
1. What do we know about water is it polar? Which parts will repell
water? Which part will attract water?
2. What is a transport protein? Why does the cell membrane need
this? How does it work?
