When a plant grows towards sunlight it is called phototropism. There are cells in the plant called auxins. These auxins originally don't face towards the sunlight but after a few days, these auxins get tricked and start slowly facing towards the sunlight. If the plant does not have a sturdy stem, then it can break.
