Phototropism
- Plant shoots are positively phototropic, meaning they grow towards light (negative tropisms are those where the plant grows away from the stimulus)
- This ensures plants maximise the amount of light they can absorb for photosynthesis
- Phototropism affects shoots and the top of stems
- This is an important mechanism of plants due to their immobility
