Answer the following question: Information: - Broccoflower refers to either of two edible plants of the species Brassica oleracea with light green heads . The edible portion is the immature flower head ( inflorescence ) of the plant . There are two forms of Brassica oleracea that may be referred to as broccoflower , both of which are considered cultivars of cauliflower ( Brassica oleracea var. botrytis ) because they have inflorescence meristems rather than flower buds when harvested . One is shaped like regular cauliflower , the other has a spiky appearance . They share a curd color that is a similar hue to that of broccoli . - Kale or leaf cabbage is a group of vegetable cultivars within the plant species "Brassica oleracea". They have green or purple leaves, in which the central leaves do not form a head (as opposed to headed cabbages). Kales are considered to be closer to wild cabbage than most domesticated forms of "Brassica oleracea". - Broccoli is an edible green plant in the cabbage family whose large flowering head is eaten as a vegetable. - In biology, a species (abbreviated sp., with the plural form species abbreviated spp.) is the basic unit of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms in which two individuals can produce fertile offspring, typically by sexual reproduction. While this definition is often adequate, looked at more closely it is often problematic. For example, in a species complex, the boundaries between closely related species become unclear or disappear altogether. Other ways of defining species include similarity of DNA, morphology, or ecological niche. The presence of locally adaptive traits may further subdivide species into infraspecific taxa such as subspecies. - Kohlrabi (German turnip or turnip cabbage; "Brassica oleracea" Gongylodes Group) is an annual vegetable, and is a low, stout cultivar of cabbage. Kohlrabi can be eaten raw as well as cooked. Edible preparations are made with both the stem and the leaves. - Brassica oleracea is the species of plant that includes many common foods as cultivars, including cabbage, broccoli, cauliflower, kale, Brussels sprouts, collard greens, savoy, kohlrabi and kai-lan. - Cabbage or headed cabbage (comprising several cultivars of Brassica oleracea) is a leafy green or purple biennial plant, grown as an annual vegetable crop for its dense-leaved heads. It is descended from the wild cabbage, "B.oleracea" var. "oleracea", and is closely related to broccoli and cauliflower (var. "botrytis"), brussels sprouts (var. "gemmifera") and savoy cabbage (var. "sabauda"). Cabbage heads generally range from , and can be green, purple and white. Smooth-leafed firm-headed green cabbages are the most common, with smooth-leafed red and crinkle-leafed savoy cabbages of both colors seen more rarely. It is a multi-layered vegetable. Under conditions of long sunlit days such as are found at high northern latitudes in summer, cabbages can grow much larger. Some records are discussed at the end of the history section. 'broccoflower' is related to which object entity through the relation of 'use'? Choices: - biology - vegetable
Answer:
vegetable
