Communication

Plants can communicate with each other through their roots. They secrete chemicals called "root exudates" into the soil, which can help dthem share nutrients and modify their behaviour. 

Gravity

Plants can sense gravity, which helps them send their roots down to find water and nutrients, and their shoots up to find light. 

Pollinators

Plants use a variety of methods to attract pollinators, such as producing sweet-smelling fragrances and sugary nectar.
