Question 17

They are used by plants for energy and growth

The sugars produced during photosynthesis are essential for plants as they serve as a primary energy source and support their growth. These sugars, particularly glucose, are utilized for various metabolic processes within the plant.

A) They increase the water content in the air

This option is incorrect because the sugars produced in photosynthesis do not directly contribute to increasing the water content in the air. While plants do release water vapor during transpiration, the sugars themselves are not involved in this process.

B) They are used by plants for energy and growth

This statement accurately describes the role of sugars produced during photosynthesis. These sugars provide the necessary energy for plant growth and development, as they are fundamental to various physiological processes and can be converted into starch for energy storage.

C) They help to cool the plant leaves

While cooling of plant leaves may occur through transpiration, the sugars produced during photosynthesis do not play a direct role in this cooling effect. This option misrepresents the primary function of sugars within the plant.

D) They attract insects for pollination

This option is incorrect as the sugars produced during photosynthesis do not primarily serve the function of attracting insects for pollination. While certain flowers may produce nectar (which is sugary) to attract pollinators, this is not a direct result of the sugars generated during photosynthesis.

Conclusion

The correct answer, "They are used by plants for energy and growth," highlights the critical role that sugars play in sustaining plant life and facilitating their growth. In contrast, the other options misinterpret the functions of sugars or relate to unrelated processes, thereby reaffirming that option B is the most accurate representation of the importance of sugars produced during photosynthesis.
