"In biology, phototropism is the growth of an organism in response to a light stimulus. Phototropism is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light contain a hormone called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the furthest side from the light. Ph… " - How does phototropism respond to stimuli

WebPhototropism—the directional bending of a plant toward or away from a light source—is a response to blue wavelengths of light. Positive phototropism is growth towards a light source (Figure 2), while negative phototropism (also called skototropism) is growth away from light. Figure 2.

WebWays how plants respond to stimuli: Because plants require sunshine to thrive, they will tilt or migrate towards the source of light. Phototropism is the name given to this type of movement. Negative phototropism occurs when a plant travels away from a light source. WebThis change in the growth pattern in response to a stimulus is known as tropism. Unlike animals, the response of a plant is regulated by the interaction of two or more plant hormones. It takes a considerably longer time to observe the stimulus. The plants use electrical-chemical means to convey information, but they have no specific tissues.

WebA tropism is the growth of a plant as a response to a stimulus, and phototropism occurs when a plant responds to light by bending in the direction of the light. Although plant physiologists (scientists who study how the processes of a plant actually work) know that this growth is caused by a plant hormone, they still do not fully understand ...
