Anatomy
Characteristics related to the internal
structure of plants have been employed for
systematic purposes for over 150 years, and they
are useful in both practical identification and
determination of phylogenetic relationships.
Anatomical characters are investigated by light
microscope study, and many can be seen in the
laboratory by use of the simplest of techniques.
Characters observable with the transmission
electron microscope (TEM) are frequently referred
to as ultrastructural those observable with the
scanning electron microscope (SEM) are often
called micromorphological.
