How does Phototropism occur in plants
Answers
Answer:
The process of phototropism is the growth of an entity in response to a light stimulus. This process is most commonly observed in plants but can also occur in other entities such as fungi. Plant cells that are farthest from light have a chemical known as auxin which is active and reacts when phototropism occurs. Tips of leaves and stems contain auxin, causing them to positively grow towards the light.
In this phenomena, the plant grows towards the sunlight hence the plant body grows in this process. When the plant body grows in the opposite direction to the sunlight, it is termed negative phototropism.
Positive phototropism is the response of a plant toward a light source, while negative phototropism causes growth in the opposite direction.
Plant roots usually use negative phototropism although additionally, they use gravitropism, which is the response to gravitational pull.
Answer:
In phototropism, a plant bend or grows directionally response to light.
