Leaf distortion in plants can be attributed to which of the following factors?

Leaf distortion in plants can occur for a variety of reasons, and one significant cause is herbicide drift or cold weather. Herbicide drift refers to the unintentional spread of herbicides from the target area to non-target plants, which can cause damage and lead to abnormal leaf shapes, curling, or discoloration. This distortion occurs because the chemicals in the herbicide affect the plant's growth processes, leading to malformed leaves.

Cold weather also plays a role in leaf distortion. When plants are exposed to low temperatures, cellular processes can be disrupted, leading to abnormal growth patterns and physical changes in leaves. Cold stress can cause leaf margins to curl or become misshapen as the plant reacts to environmental stressors.

While infestation by insects, fungal infections, and nutrient deficiencies can indeed affect plant health, the specific combination of herbicide effects on growth patterns and cold weather conditions makes herbicide drift or cold weather particularly relevant in causing leaf distortion.
