Dissection of a Root
Nodule
Examine roots under
the microscope on low power. Sketch and
intact nodule and root here:
Obtain a razor
blade, slice the nodule open sagitally (so you can see the cut surface of one
side). Describe the appearance of your nodule.
If yours “didn’t work’ describe the appearance of someone’s who
did. Sketch
What process occurs
in the nodules?
What conditions are
indicated by what you observed in a nodule
What compound
provided by the clover plant provides this condition?
What is the
importance of this process in the biosphere?
