WHAT DOES PHOTOTROPISM MEAN IN ENGLISH?

phototropism

Phototropism

Phototropism is the growth of organisms in response to light. It is most often observed in plants, but can also occur in other organisms such as fungi. The growth or movement of a plant part in response to a source of light. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the farthest side from the light. Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism. Most plant shoots exhibit positive phototropism, and rearrange their chloroplasts in the leaves to maximize photosynthetic energy and promote growth. Roots usually exhibit negative phototropism, although gravitropism may play a larger role in root behavior and growth. Some vine shoot tips exhibit negative phototropism, which allows them to grow towards dark, solid objects and climb them. The combination of phototropism and gravitropism allow plants to grow in the correct direction.

Definition of phototropism in the English dictionary

The definition of phototropism in the dictionary is the growth response of plant parts to the stimulus of light, producing a bending towards the light source. Other definition of phototropism is the response of animals to light; phototaxis.
