Phototropism
Plant shoots display positive phototropism: when illuminated from one direction, the shoot proceeds to grow in that direction.
Proposed Mechanism ...

phototropism: the bending and turning of the plant stem toward a light source.
phyla: related classes grouped together (singular, phylum).

phototropism The reaction of plants to light in which the plants bend toward the light. Plant response to light by unequal growth caused by concentration of the plant hormone Indole Acetic Acid (IAA, an auxin) on the darker side of the plant shoot.

phototropism The bending of a plant toward a unidirectional light source.
photovoltaic cell An energy-conversion device that captures solar energy and directly converts it to electrical current.

Phototropism growing or leaning in response to light
(photo = light; tropo = turn change)

Phycomyces, a fungus, also exhibit phototropism
A tropism is a biological phenomenon, indicating growth or turning movement of a biological organism, usually a plant, in response to an environmental stimulus.
