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