Brassica rapa species. Since the turnip had been named first by Linnaeus, the name "Brassica rapa" was adopted. Many butterflies, including the small white, pollinate the "B. rapa" flowers. Brassica rapa Brassica rapa is a plant consisting of various widely cultivated subspecies including the turnip (a root vegetable); napa cabbage, bomdong, bok choy, and cime di rapa (leaf vegetables); and "Brassica rapa subsp. oleifera", an oilseed which has many common names, including "turnip rape", "field mustard", "bird rape", and "keblock". The oil made from the seed is sometimes also called "canola" or "colza", which is one reason why it is sometimes confused
Vegetable oils as alternative energy carbon dioxide (CO) out of the Earth's atmosphere to make vegetable oil. The same CO is then put back after it is burned in an engine. Thus vegetable oil does not increase the CO in the atmosphere, and does not directly contribute to the problem of greenhouse gas. It is really a way of catching and storing solar energy; it is a renewable energy. However, as with other "renewable" energy sources, there may be a (relatively small) carbon footprint associated with production or distribution of vegetable oil. Vegetable oil is far less toxic than other fuels such as gasoline, petroleum-based
