I’m a plant. I was green but now I’m changing colour

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.

About argylesock

I wrote a PhD about veterinary parasitology so that's the starting point for this blog. But I'm now branching out into other areas of biology and into popular science writing. I'll write here about science that happens in landscapes, particularly farmland, and about science involving interspecific interactions. Datasets and statistics get my attention. Exactly where this blog will lead? That's a journey that I'm on and I hope you'll come with me.

  1. I am actually writing my bachelor thing about anthocyanin, one of the flavonoids involved in this, but not in relation to autumn colours, in relation to its function within plants during the rest of the year 🙂

      How interesting! I hope you’ll blog about it.

      My post here was going to be more of an introduction to photosynthesis, talking about all the leaf pigments and what they do. Then the autumn began and nahrvalur wrote fabulously about it, so I published the above. My overview of leaf pigments is still on the to-blog list.

        I might do. I really love photosynthesis, the 3 different types are amazingly interesting, and my favourite is CAM photosynthesis, cos it is really smart.
