It is crucial to distinguish between toxins—harmful substances produced within living organisms—and toxicants, which are synthetic chemicals created by artificial processes.
Phototropism and Scutotropism: Plant Responses to Light
One of the most fascinating abilities of plants is their response to light through a phenomenon known as phototropism. Plants possess specialized light-sensitive proteins called phototropins and phytochromes, which help them detect light direction and intensity.
