Angiosperms, Abnormal Function, and Adaptation
Find an angiosperm that has modified leaves, stems, roots or
flowers that do not function in the normal manner, or that function in an
unusual manner.
Angiosperms (flowering plants) are the largest Phylum in the
plant kingdom (Angiospermophyta is also called Anthophyta or Magnoliophyta).
These plants have true roots, stems, leaves and flowers. The roots grow into
the soil to anchor the plant in place and take up water and nutrients. The
leaves are above ground and act as the main organs for photosynthesis. Stems
act as above ground support for the plant and operate as conduits to move
nutrients and water throughout the plant. Flowers contain the male and female
reproductive organs of the plant.
With these anatomical features in mind, do some research to
find an angiosperm that has modified leaves, stems, roots or flowers that do
not function in the normal manner, or that function in an unusual manner.
Explain how this modification helped the plant adapt to its environment
Example: A California Barrel Cactus has spines in place of
leaves to reduce water loss.
