Tropism
The responses of plants to external stimuli is called Tropism.Here are some tropisms:* Chemotropism, movement or growth in response to chemicals * Geotropism (or gravitropism), movement or growth in response to gravity * Heliotropism, movement or growth in response to sunlight * Hydrotropism, movement or growth in response to water * Phototropism, movement or growth in response to lights or colors of light * Thermotropism, movement or growth in response to temperature.
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
thigmotropism
hydrotropism is the positive response that plant roots give when there is water or a moisture gradient nearby, which means they growth towards the water
The green color fades and the plant tries to grow taller to reach the light.

Plant growth in response to touch is called thigmotropism.

Light. Tropisms are growth responses to stimuli. Photo-tropism = light-growth

Gravitropism (also known as geotropism) is a turning or growth movement by a plant or fungus in response to gravity. It is a general feature of all higher and many lower plants as well as other organisms. Wikipedia
