ruler for any measurements that need to be taken.
Part A Structural Modifications
Look for the plants associated with the structural modifications in the
greenhouse. There are tree categories of Structural Modifications: Leaves,
Stems and Roots. You will be instructed by your Lab Instructor to which plants
you are to identify. Please use only the plants you are told to observe.
Plant #1 (2pts)
Name of plant
What structure is modified?
How is it modified?
What advantage does this modification provide the plant?
Plant #2 (2pts)
Name of plant
What structure is modified?
How is it modified?
What advantage does this modification provide the plant?
Plant #3 (2pts)
Name of plant
What structure is modified?
How is it modified?

Part B
Floral morphology
Look for the plants associated with the floral morphology in the green house. These plants have a flower modification
that will need to be identified.
There are four categories of floral modification:
Wind Pollinated plants, Bee Pollinated plants, Bird pollinated plants, or Butterflies/Moth pollinated plants
Plant #4 (2 pts)
Name of plant
How might this plant pollinated?
Include Measurements (cm) and what was being measured
Estimate the size of the pollinator,
be sure to justify your answer with complete sentences.
Plant #5 (2 pts)
