The tendency of plants to alter their growth in response to the direction of light shining on them is called phototropism. Generally the above ground shoot portion of plants tends to grow toward the light, exhibiting positive phototropism. This...

Means attracted to light. It is usually applied to certain plants and vegetative matter to indicate that they grow towards, or whose flowers move to face, the...

Phototropism is directional plant growth in which the direction of growth is determined by the direction of the light source. Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is...

Research on phototropism has had far-reaching consequences in the field of plant biology, from helping to refute the ancient misconception of plant insensitivity to the environment to the discovery of the plant hormone auxin and the identification of the phototropin photoreceptors. In this essay,...

Phytochromes A and B Mediate Red-Light-Induced Positive Phototropism in Roots1 The interaction of tropisms is important in determining the final growth form of the plant body. In roots, gravitropism is the predominant tropistic response, but phototropism also plays a role in the...

The following presents a bio essay on phototropism, gravitropism, and thigmotropism.
