Monocot is short for monocotyledon.  It describes a plant
who's seedlings bear only one leaf.  Grasses, orchids and
lilies are monocotyledons.

Dicot is short for dicotyledon.  It describes a plant who's
seedlings bear two leaves.

A Gymnosperm is a member of the class Gymnospermae. 
Contrast gymnosperm with angiosperm.  Angiosperms bear seeds
within a closed ovary.  Gymnosperms do not.

"gummy exudate" describes a thick, sticky substance produced
on the outside of a plant.

You have me on that one.  A cotyledon is the first leaf
produced on a seedling.  I know of plants that are
dicotyledonous (2 seedling leaves) and monocotyledonous (1
seedling leaf).  By extension I suppose "noncotyledonous"
would refer to a plant who's seedlings bear no leaves.
