Describe positive photo tropisms of stems
- Light --------> Growth -------> towards light.
Where the light is coming from the plant will grow towards the light. If the light is coming from the left than the plant will grow to the left.
- The light from one side causes the movement on the opposite side.
- Auxin is a hormone that causes growth.
A little more detail Andrew. Look around at some of the other students work.
