1. Roots: Detecting Nutrients and Chemicals
Beneath the soil, plant roots function as remarkably sensitive detectors, constantly sampling their surroundings. These roots “taste” for essential elements like water, minerals, and even recognize toxic compounds, helping the plant navigate complex underground environments. For instance, maize roots can sense patches rich in nitrogen, prompting rapid root growth in that direction for maximum nutrient uptake. This chemical awareness allows plants to thrive and avoid dangers lurking below. Learn more
