1. Leaf structure

2. What functions do the cells in a leaf need to perform?  Leaf is a plant organ.  Cells are specialized so that form matches function.  List as many functions as you can think of for cells found in a plant leaf.

3. Task One  View a cross section of a leaf.  Draw in detail and with complete accuracy.  Label any recognizable cell structures.  Make a table listing at least three different cell types and what you think their function is.  In color and with total magnification.

4. Task Two  Remove a single leaf from a bean plant.  Paint a narrow strip of nail polish on the top and the bottom of the leaf.  Let dry.  Place a strip of scotch tape over the nail polish, press down, and then gently remove.  Place tape directly on a microscope slide and draw what you see.  What is that mysterious structure that looks like lips?  Compare the upper leaf surface with the lower leaf surface.

5. Analysis Questions  What is the chemical formula for photosynthesis?  Make a final list of what you think specialized cells within a leaf must do.
