Biology 11 – A Virtual Tour of the Cell Membrane, Nucleus and
Cytoplasm
Go to http://personal.tmlp.com/Jimr57/textbook/chapter3/chapter3.htm Scroll down to the table
of contents and click on the structure you want. In this activity we are
concerned with three main structures: the cell membrane, the nucleus,
and the cytoplasm.
1. The Cell Membrane

(A)
Name the three main parts of the cell membrane:
(b)
Draw and label a phospholipid molecule to show the hyrdophobic
“tail” and hydrophyillic “head”.
(c)
List the three types of proteins and describe the function of
each.
