Plant Collection
Make a collection of seed plants consisting of at least 12 different species.
Include at least 2 gymnosperms in your collection. Collect enough of each plant so that
you can demonstrate the correct classification of each as either gymnosperm or
angiosperm. (Usually a small branch or stalk will do, though in some cases you may
want to include the roots. Try to be sensitive about the plant's environment: Do not
uproot or defoliate rare plants and do not remove materials from a park!) Plants can be
preserved by wrapping them in plastic or by pressing them between sheets of cardboard.
For each plant you have collected, clearly identify it as an angiosperm or gymnosperm
and state how you made this classification, referring to structure(s) evident on the
specimen.
Also, classify each flowering plant as either a monocot or dicot. For each plant you
classify, state how you decided on your classification, referring to structure(s) evident on
the specimen.
