(2.81) Describe positive phototropism of stems

·         Positive phototropism is towards the light
·         A plant that receives uniformed light from above will grow upwards
·         A plant will bend in the growth towards the light if it is a lateral light source
·         Auxin (plant hormone) goes away from the light and therefore causes more growth on the area away from the light
