Cucumber.

A cucumber is the long, thin, edible produce of the vine of the Cucumis sativus plant. Botanically, the cucumber is considered a fruit. However, it is usually treated as a vegetable in the ways it is prepared and consumed. Cucumbers have been cultivated and eaten for more than three thousand years. They may have been among the first plants to be cultivated in a greenhouse-type structure, and they remain a popular choice for contemporary home gardeners. Although they are up to 96 percent water, cucumbers contain many nutrients and are low in calories. They are among the most common foods to be pickled.
