study.

What primary meristems are produced by the apical meristem?
Understand the relationship of the growing regions such as apical meristem,
leaf primordial, bud primordial, leaf, node, internode axillary bud,
phytomere, and
leaf traces and gaps.
What structural differences exist between monocots and other angiosperms?
Understand the three basic types of organization I the primary structure
of stems in cross secton. (continuous hollow cylinder, discrete ring
of bundles, scattered
vascular bundles.)
Know the structures and functions of those structures found in vascular
bundles of dicots and monocots.
