positive phototropism
The stimulus that produces growth of the plant toward light is called phototropism. It is caused by the presence of blue light, specifically light in the 440-470nm wavelength range, which is detected by the plant's photoreceptor molecule called phototropin. This photoreceptor triggers a signaling pathway that stimulates cell elongation on the shaded side of the plant, resulting in growth towards the light source.
Light. Tropisms are growth responses to stimuli. Photo-tropism = light-growth
Most hippos respond to stimuli in an aggressive manner. Hippos are known for their aggression toward people and have even been known to attack crocodiles.

I think you're talking about phototropism.
phototropic (details from another answer) movement of or growth of plant in response to external stimulus. e.g. growth of root towards gravity - geotropism growth of shoot towards the light - phototropism hydrotropism is exhibited by lengthening of roots towards water source and finally, thigmotropism is growth towards solid objects -support by climbers
Tropism: is the growth response of a plant that results from certain stimuli. Tropism can be positive, in which case the plant will bend toward the stimulus, or negative, in which case the plant will bend away from stimulus. Taxis: Taxis in animals is the responsive movement of going toward or away from an external stimulus.
The external stimuli involved are as follows: the eyes see the warm coloring of peach, the nose smells the scent of the ripe peach, and your salivary glands start releasing saliva to help dissolve the peach itself. The internal stimuli is mainly your brain, which processes all of this information that the other senses are sending, and sends, for lack of a better word, "spark" to your arm and hand so you can bring the peach toward your mouth and eat it.

It's a survival mechanism. Reacting quickly can mean the difference between life and death in some situations (ie- a large boulder rolling down a hill toward an animal; that animal is going to move as soon as they notice the boulder). In other cases, external stimuli could mean something good, like sunlight signalling the beginning of the day and thus the beginning of a diurnal animal's activity period.
