Which statement is best supported by the data regarding wheat plants and ultraviolet light?

The statement that wheat plants exposed to high-intensity ultraviolet light produce fewer seeds is supported by observations related to the effects of UV exposure on plant health and reproductive success. High-intensity ultraviolet light can cause damage to plant tissues, leading to stress responses that may inhibit growth and reproductive processes. When plants are subjected to excessive UV light, it can result in physiological stress, which often manifests as reduced seed production.

This relationship between high UV exposure and decreased seed output highlights the importance of light intensity and quality in plant development, particularly in terms of reproductive capability. High-intensity light, especially in the ultraviolet spectrum, can be detrimental rather than beneficial, emphasizing the delicate balance that plants must maintain regarding their light environment for optimal growth and reproduction. Thus, the statement accurately reflects the adverse effects of high-intensity ultraviolet light on wheat plants, leading to the conclusion that these plants produce fewer seeds under such conditions.
