WHY DO LEAVES CHANGE COLOUR?


Have you ever wondered why the leaves change colour as they do during autumn? When you think of the season Autumn, you think of colder weather, a slight chill in the air leaves changing colour and falling off from trees. But why does this happen? Do leaves have some kind of superpowers that make them change colour? Even though that would be so awesome, there’s actually a scientific reason for this!

To do this you will need a big leaf and a magnifying glass so you can have a closer look at your leaf.
Plants are green because of a chemical called chlorophyll. What chlorophyll does is give plants its colour green and not only that but it also helps capture energy from the sun.

Leaves then use this solar energy to make sugar, yes squad members’ leaves can make sugar, this sugar is what the plants then eat.

Plants have other chemicals called pigments which give off red, orange, yellow and sometimes even purple colour.
If you’ve eaten carrots, cabbage or cherries – then you’ve not only seen the pigments but you’ve eaten them! All of the colour pigments have special jobs, but only chlorophyll can make the sugar that the plants need to live.

As the season moves into autumn and winter, the trees make less chlorophyll so we’re able to see the other colours. Once the leaf has turned from green to one of the other colours, they begin to fall. This is because without their chlorophyll they don’t make energy!

So when you step outside and see a tree that was once green and now is orange, remember that that colour was there all along, and Autumn is just their time to shine!
