Cell City
 Purpose - To make mental connections
between cell structures and their functions in
order to better understand the role of the
various organelles and how they interact.
How we will do this - Make analogies between
the functional parts of a city and the functional
parts of a cell.
Cell Membrane
 Description –thin membrane
composed of phospholipids that
is imbedded with proteins
 Purpose – selective barrier

Cytoplasm
 Description –clear in color and has a gellike appearance. Composed mostly of
water and also contains enzymes, salts,
organelles, and various organic molecules.
 Purpose - The cytoplasm helps to move
materials around the cell and also dissolves
cellular waste.
