Answer to q. 1

Your first diagram should be similar to that shown in Fig. 35-3 part 1, and your second diagram should
be similar to that shown in Fig. 35-3 part 3.

Answer to q. 2

Monocot and eudicot stems are similar in that they have an epidermis surrounding a region of ground
tissue and vascular bundles. In eudicots, the vascular bundles are arranged in a ring that surrounds a
central pith; the ground tissue outside the ring is cortex. In monocots, the vascular bundles are
scattered throughout the ground tissue, and as a result pith and cortex are lacking.
