As students observe several slides of tissue cross-sections, one simple key they can use to determine if the slides come from dicots or monocots is to analyze the <em><u>vascular bundles</u></em><em><u>.</u></em>
A vascular bundle is described as a portion of the transport system of vascular plants. These bundles are microscopically different in Monocots than they are in Dicots, which will allow students to tell them apart through the tissue slides.
The difference is that monocots contain <em><u>randomly scattered </u></em><em><u>bundles </u></em><em><u>located throughout the </u></em><em><u>stem</u></em><em><u>.</u></em> On the other hand, <u>dicots </u><em><u>have their vascular </u></em><em><u>bundles </u></em><em><u>more neatly organized in </u></em><em><u>concentric circles</u></em><em><u>.</u></em> These microscopic differences can serve as a key to be used by the students to classify the tissue samples they are studying.

The Galápagos Islands' 14 species of finches all evolvedfrom one ancestral species, which arrived from the South American mainland about two to three million years ago. That original species branched out into many others, with each one specialized for different roles.
The answer is mutations in a gamete, I believe.
