"Plants are often seen as passive organisms, rooted in one place and largely
unable to react to the world around them.

But a new field of research is challenging these assumptions and showing that
plants are as sophisticated as animals in detecting and adjusting to
environmental signals.

Plants can perceive light through specialised proteins, detect sound vibrations
and respond to touch via mechano-sensitive channels, recognise chemical signals
released by neighbouring plants, and even retain memories of past experiences
through changes in their DNA.

My own research focuses on how plants detect the passage of time as part of
their seasonal cycle, but that is merely one aspect of a major reconsideration
of their sensory capacity – and the parallels with animal senses."
