How does the plant utilize glucose after its production in photosynthesis?

After glucose is produced during photosynthesis, plants primarily utilize it for energy and as a building block for structural components. Glucose serves as a crucial energy source that fuels various cellular processes, enabling the plant to grow, reproduce, and maintain its metabolic functions.

Additionally, glucose can be converted into other carbohydrates, such as starch and cellulose. Starch acts as a storage form of energy that plants can tap into during periods of low photosynthesis, like at night or during winter. Cellulose, on the other hand, is a vital structural component of the plant cell wall, providing support and rigidity to the plant structure.

This dual role of glucose—providing immediate energy and contributing to the plant's structure—is fundamental for the plant’s survival and growth. Other options do not accurately reflect the primary uses of glucose in plants. For instance, although transportation of nutrients happens in roots, it's not specifically related to glucose utilization. Creating more water and repelling pests are also processes not directly associated with the primary roles of glucose derived from photosynthesis.
