- If light comes from all directions the stem will grow forwards and upwards.
- If light comes from lateral light source the stem will start growing towards the light.
- Light on one side, causes movement of opposite side of a compound, Auxin (plant hormone).
- Auxin causes more growth to the plant which makes the plant grow in the other direction an also causes the plant to bend.
- Cell division is called mitosis which means that the cells multiply.
