Final answer:
Yes, it is true that two plant sources of sucrose are sugar cane and sugar beet. These are the main contributors to commercial sucrose production, with sugar cane requiring a tropical climate and sugar beet growing well in various climates.
Step-by-step explanation:
True, two plant sources of sucrose are sugar cane and sugar beet. These two sources are the primary contributors to the commercial availability of sucrose, commonly referred to as table sugar, beet sugar, or cane sugar. Sugar cane and sugar beets are processed through the evaporation of water and recrystallization to extract pure sucrose. While sugar cane requires a tropical climate with plenty of rainfall and a long growing season for optimal yields, sugar beets are more adaptable and can be grown in a variety of climates, including desert and colder regions. Furthermore, about half of the US granulated sugar production is derived from sugar beets, showcasing their significance in the agriculture and food industry.
In comparison, the cost and geography of sugar production are key factors influencing why high fructose corn syrup (HFCS) has displaced granulated cane and beet sugars in the American diet. However, the production of sucrose through photosynthesis is a process that all plants, including sugar cane and sugar beets, utilize to convert water, carbon dioxide, and sunlight into carbohydrates, such as sucrose.
