Modified Stem

This is a photo of onions. Onions are an example of plants that have a modified stem. In the case of these onions, they have a modified stem known as a bulb, specifically known as a tunicate bulb. The "tunicate" comes from the dried outer layers that enclose the it. In bulbs the modified stem has all of the nutrients stored in it, and it grows underground.
