Most of the plants we’re familiar with are green. It’s because they contain chlorophyll.
Chlorophyll is a pigment that lets the plant make itself from air, water and sunlight, plus small amounts of minerals. Making yourself from sunlight is called photosynthesis. Photo: light. Synthesis: making. Harold Baum was so impressed that he wrote, ‘I cannot synthesise a bun by simply sitting in the sun.’ If plants didn’t photosynthesise, the rest of us wouldn’t have anything to eat.
Here in Northern England the deciduous plants’ colours are changing. Soon their leaves will fall. My fellow blogger nahrvalur, a few hundred miles away, tells us why this happens every autumn.
