Maize stem (monocot) One significant difference can be observed microscopically: the vascular bundles (the cells that carry water and nutrients up and down the stem) show a significantly different arrangement in these two groups. Monocots have the vascular bundles scattered randomly throughout the stem. The vascular bundles of dicots are arranged in concentric circles.

Monocots and dicots can be distinguished by the arrangement of the vascular bundles.

Looking like a stained glass window, this is the remains of the seed pod of one of last summer's garden flowers, Lunaria annua (commonly known as honesty, because the dry seed pods resemble silver coins), magnified and viewed using polarised light.

The red blood cells of amphibians contain contain a nucleus, which is visible as a dark purple dot in the center of each cell. In contrast, the red blood cells of mammals do not possess a nucleus.
