Question

The form of sugar transported through phloem is

• A. Ribose
• B. Glucose
• C. Sucrose
• D. Fructose

Answer 1

The correct option is C

Sucrose

The correct option is C.

Explanation of correct option:

1. The photosynthesis-produced sugars are transported vertically, horizontally, and laterally to all other organs, mostly through the phloem, in the form of sucrose.
2. Disaccharide sugar sucrose is made up of the subunits of glucose and fructose.
3. It is the primary component of white sugar and is naturally produced by plants.

Explanation of incorrect option:
Option A:

1. The body spontaneously produces the sugar ribose from meals.
2. It is a naturally occurring component of DNA and RNA and is necessary for numerous bodily activities.
3. In individuals with specific genetic abnormalities that limit the body's ability to produce energy, more ribose may avoid muscle weariness.

Option B:

1. A simple sugar is glucose.
2. The most prevalent monosaccharide, a type of carbohydrate, is glucose.

Option D:

1. A monosaccharide is a form of sugar that includes fructose.
2. Fructose has four calories per gram, much like other sugars.
3. Because it is largely found naturally in many fruits, fructose is also referred to as "fruit sugar."

Final answer: The form of sugar transported through phloem is sucrose.
