A plant's response to gravity is called gravitropism or geotropism.
Phototropism, where the plant "turns" to arrange its leaves for better exposure to light. This process is regulated by growth regulators in the plant. Photo = light Tropism from the Greek "trope" or turning. See picture
The growth response of a plant to touch is called thigmotropism. Thigmotropism is the phenomenon where plants grow or orient themselves in response to mechanical contact or touch. Examples include plants like vines that coil around structures for support.
Geotropism is a plant growth or movement in response to gravity. Upward growth of the plant's parts against gravity is called negative geotropism, whilst downward growth of roots is called positive geotropism.
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.
A plant that responds to light is said to be photosensitive, and it is said to have the property of photosensitivity.
The growth of a plant part towards the Earth is called gravitropism. This is a plant's response to gravity, where roots grow downward (positive gravitropism) and stems grow upwards (negative gravitropism).
Plant growth hormones e.g. IAA.
