Sugarcane
Sugarcane is a tall tropical grass cultivated for its sucrose-rich stems, which are processed into sugar, ethanol, and other products.
Saccharum: Saccharum is a genus of tall perennial grasses that includes cultivated sugarcane and its wild relatives. Cultivated sugarcane belongs to this genus, whose species contributed to modern crop varieties.
Sugarcane mill: A sugarcane mill extracts juice from harvested cane and processes it into raw sugar and by-products. The mill begins the industrial conversion of stalk sucrose into marketable products.
Sugar: Sugar is a sweet, soluble carbohydrate, usually referring in food contexts to sucrose. Cane is one of the world's principal crops for producing commercial sugar.
New Guinea: New Guinea is a large island north of Australia, home to long-established agricultural societies and diverse plant domestication. Evidence points to New Guinea as an early center of sugarcane domestication.
Sugarcane plantation: A sugarcane plantation is a large agricultural operation devoted to cultivating and harvesting sugarcane. Plantation production shaped the scale and labor organization of cane cultivation in many regions.
C4 carbon fixation: C4 carbon fixation concentrates carbon dioxide around RuBisCO, reducing photorespiration in hot, bright environments. This photosynthetic pathway helps sugarcane grow efficiently in tropical sunlight.
Sugar refining: Sugar refining purifies raw sugar by removing color, minerals, and other impurities. Refining follows milling when raw cane sugar is converted into white sugar.
Ethanol fuel: Ethanol fuel is ethyl alcohol used alone or blended with gasoline for combustion engines. Fermentable cane sugars and molasses can be converted into fuel ethanol.
Saccharum officinarum: Saccharum officinarum is a sugarcane species with thick, sugar-rich stalks, historically cultivated for sugar. This species contributed heavily to the high-sucrose traits of modern cane.
Atlantic slave trade: The Atlantic slave trade forcibly transported millions of Africans across the ocean, chiefly from the sixteenth to nineteenth centuries. Sugar plantations in the Americas were a major site of enslaved labor and colonial wealth.
