Verified step by step guidance
1
Understand the role of glucose in plants: Glucose is a simple sugar that is a product of photosynthesis, the process by which plants convert light energy into chemical energy.
Recognize that glucose serves as a building block for more complex carbohydrates: In plants, glucose molecules can be linked together to form starch, which is a polysaccharide.
Identify the function of starch in plants: Starch acts as an energy storage molecule. Plants store excess glucose in the form of starch, which can be broken down into glucose when energy is needed.
Differentiate between the roles of glucose and other plant components: While glucose is involved in energy storage, cellulose (another polysaccharide) is used for structural support in cell walls, not glucose directly.
Conclude that the primary function of glucose in plants is to serve as an energy source, primarily stored as starch, which can be utilized when the plant requires energy.
