On a shelf lined with terra-cotta pots, herbs bend their stems toward the nearest window. In a field of golden wildflowers, leaves rotate with the path of the sun. In a dappled forest, vines twine up ...

Researchers have identified key structures in photosensitive plant tissue that allow them to determine the direction of light, leading to positive phototropism. A recent research collaboration between ...

Plants use a light-sensitive tissue to detect the origin of light and position their organs for optimal photosynthesis. This tissue generates a light gradient using the optical properties of the ...
