The tendency of growing plant organs to move or curve under the influence of light. In ordinary use the term is practically synonymous with heliotropism.
exhibiting movement in a direction toward (positive phototropism) or away from (negative phototropism) a source of light.
the tendency of plans to move or grow towards light
a growth response of a plant to a uni-directional source of light.
The bending of plants in response to a light source, usually in response to differential auxin concentrations in the stem.
the response and movement of plants towards light
a term used for the theory of plants growing towards light.
the bending and turning of the plant stem toward a light source.
Gr. photos: light + trope: a turning] • A directed plant growth response to light.
an orienting response to light
Photo-mediated degradation of epidermal cell auxin, resulting in decreased cell elongation on the light-exposed side of the plant and, hence, bending of the plant toward the light source.
the specific movement of a plant part toward a light source.
The plants response to light by moving in relation to the source of the light. Shoots and leaves are positively phototropic. Roots are usually negatively phototropic, or have no response. This is the reason for ‘turning' your plants on a daily basis to ensure even growth. This can also be used to advantage by producing ‘standards' more quickly by placing a chosen plant or cutting in a place where the light level is lower - the plant will grow upward in an attempt to reach the light.
A growth-mediated response of plants or microorganisms to stimulation by visible light.
fo-toe-TROP-iz-um A plant's growth towards unidirectional light. 578
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. PICTURE
The gravitation of a plant part toward a light source.
The growth of a plant in response to light.
Growth or movement of a sessile organism toward or away from a source of light.
A phenomenon describing the tendency of African Violets and other plants to bend toward the light. This tendency is activated by a light-sensitive hormone called auxin.
Growth or movement toward or away from a light source.
Phototropism is the response of an organism to light, usually expressed as movement of a part of an organism toward or away from the stimulus of light, as when trees or plants grow toward sunlight.
the bending of a plant toward the direction of more intense light. Refer a Friend to Garden Simply!

Phototropism is directional plant growth in which the direction of growth is determined by the direction of the light source. It was formerly called heliotropism. Phototropism is one of the many plant tropisms or movements which respond to external stimuli.
