Which of the following is NOT a function of plant roots?

Plant roots serve several essential functions that contribute to the overall health and stability of the plant. Among these functions, absorbing water and nutrients from the soil is one of the primary roles. Roots effectively take up essential minerals and water, which are necessary for the plant’s growth and metabolism. Additionally, roots help anchor the plant securely in the ground, providing stability against various environmental factors like wind and erosion. They also play a role in storing food and nutrients, which can be critical for the plant’s survival during periods of dormancy or when resources are scarce.

On the other hand, photosynthesis is primarily the function of the leaves and green stems of the plant, where chlorophyll captures sunlight and enables the conversion of carbon dioxide and water into glucose and oxygen. This process occurs in the chloroplasts of plant cells, not in the roots. Therefore, since photosynthesis is not a function performed by the roots, it is identified as the correct response to the question.
