Phototropism
Phototropism is a type of plant response that involves directional growth due to light. It allows a plant to grow towards a light source, which can be beneficial in providing an optimal environment for photosynthesis.
Phototropism is directional, meaning that the plant will grow towards the light and not away from it. The response is triggered by light receptors in the plant’s cells, which activate hormonal pathways that direct the plant’s growth.
Phototropism is most commonly observed in the growth of plant stems, which will grow towards the light to maximize exposure to the sun. However, phototropism can also occur in the leaves, with the tips of the leaves often bending towards the light.
