Question

a disaccharide is a carbohydrate made of two monosaccharides bonded together. one example of a disaccharide is sucrose.
in plant cells, glucose and fructose can react to form sucrose. plants with high levels of sucrose, like beets and sugar cane, are harvested by people to make granulated sugar for baking and cooking.
the model shows the chemical structure of sucrose.
select the true statements.
beets are a source of sucrose.
sucrose can be made in plant cells.
monosaccharides are made by joining two disaccharides.
fructose and glucose have the same chemical structure.

Explanation:

• The text states that plants like beets (which are harvested for sugar) have high levels of sucrose, so "Beets are a source of sucrose" is true.
• It also mentions that in plant cells, glucose and fructose can react to form sucrose, so "Sucrose can be made in plant cells" is true.
• Monosaccharides are the building blocks, disaccharides are made by joining two monosaccharides, so "Monosaccharides are made by joining two disaccharides" is false.
• The chemical structure model shows glucose and fructose have different structures (e.g., different arrangements of -OH groups), so "Fructose and glucose have the same chemical structure" is false.

Answer:

Beets are a source of sucrose.
Sucrose can be made in plant cells.
