Question

How does the colour of tomato change from green to red?

Answer 1

As the tomato ripens, its colourstarts to change from green to yellow and then eventually to red. This is due to the breakdown of chlorophyll, which in turn synthesises a red carotenoid (another pigment group), lycopene. When ripe, the carotenoid caneasily be seen as the dominantcolour of the tomato, ie red.

Answer 2

hey

It is changed by using a litmus paper which turns into red and indicate that tomato is an acid

☆ when a blue litmus changes its colour to red then it is an acid
