auxins
Auxin is the chemical that promotes phototropism in plants. Auxin is produced at the tips of plant stems and helps cells elongate, causing the plant to bend towards a light source.
Yes, phtotropism is a plant's response to light. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism.

Both geotropism and phototropism involve plant growth responses to external stimuli. Geotropism is a plant's growth response to gravity, which helps roots grow downward and stems grow upward. Phototropism is a plant's growth response to light, guiding plants towards a light source for photosynthesis. Both tropisms aid plants in optimizing their growth and development.
Phototropism is the growth response of plants to light, where they grow towards a light source. This response is regulated by the plant hormone auxin.
Phototropism is a plant's growth response to a light source, determining which direction it grows in. Positive Phototropism is the tendency for a plant to grow towards the light; Negative Phototropism is when it grows away from the light.
Phototropism is the word for it when plants grow towards/away from a source of light. There's actually positive and negative ways of phototropism: If the phototropism is positive it grows towards the light, and if the phototropism is negative, it grows in the direction away from the light.
A creep in plants is caused by a hormone called auxin which promotes elongation of cells, causing the plant to grow horizontally along the ground. This response is a form of directional growth called phototropism, where the plant is trying to reach for sunlight.
Phototropism is the growth response of plants to light, where they bend towards the light source. This directional growth allows plants to optimize their exposure to sunlight for photosynthesis. Phototropism is mainly controlled by the plant hormone auxin.
