I FINALLY FIGURED IT OUT!!

The vascular bundle of a monocot stem LOOKS LIKE THE ALIENS FROM INDEPENDENCE DAY while the vascular bundle of a dicot stem LOOKS LIKE THE FOOTPRINTS OF GODZILLA.

The vascular bundle of a dicot plant has TWO extra components - VASCULAR CAMBIA (sing., cambium) and TRACHEIDS. The vascular cambium is the reason why dicots have FIRMER STEMS. A tracheid is an elongated cell inside the xylem that TRANSPORTS WATER.

There are five kinds of secondary walls that may be inside a tracheid. There's the annular, helical, scalariform, reticulate and pitted.

THERE. I SUMMARIZED IT ALL.

I AM NOT GOING TO FAIL BOTANY I AM NOT!!!!
