The private life of plants

Plants live on a different time scale, and even though their life 
is highly complex and often surprising, most of it is invisible 
to humans unless events that happen over months or even 
years are shown within seconds.The adaptations are often complex, 
as it becomes clear that the environment to which plants must 
adapt comprises not just soil, water and weather, but also other plants, 
fungi, insects and other animals, and even humans. The series shows 
that co-operative strategies are often much more effective than 
predatory ones, as these often lead to the prey developing methods 
of self-defense – from plants growing spikes to insects learning 
to recognise mimicry.
