How do flowers/plants turn to face the sun/light?

How does this actually work?

FlowersBirthday FlowersSympathy FlowersHi Emjay,





The process is called phototropism.





Generally speaking, it is where a phytohormone, auxine, is stimulated by light and causes the plant%26#039;s cells to elongate.





Growth toward the source of light is called positive phototropism and growth away from the light source is negative phototropism.





When a plant displays the characteristic of its flower %26quot;facing%26quot; the sun, the cells on the shady side of the flower%26#039;s stem elongate, thereby bending the flower over to %26quot;face%26quot; the sun.





I hope this helps.
