As part of my time off I took yet another visit to kew gardens with a friend who had never been before. Every time I go I learn a little something different and this time I was wondering about colours of plants. Most plants are green in colour but not all! Today I thought we would explore why this is?
Why are plants green?
Plants are green because their cells contain chloroplasts which have the pigment chlorophyll. This pigment absorbs deep-blue and red light, so that the rest of the sunlight spectrum is being reflected, causing the plant to look green.
What other plant colours can you get?
Think of a colour any colour, you can almost definitely find a plant that colour! Often the colours are found in the flowers but some plants have different coloured leaves too!
Why do plants have different colours?
Often the colours are an adaptation to attract different pollinators. The colours come from different chemicals that absorb different wavelengths of light leaving different colours behind!
Hope you feel like you’ve learnt something a little different this Wednesday! See you on Sunday!
