Question

why is tomato red in colour?

Answer 1

the colour of fruits and flowers in plants is due to the presence of chromoplast ( plastids) . so , the tomato is also red in colour.

Answer 2

Tomatoes contain two pigments for photosynthesis—chlorophyll, which is green, and lycopene, which is red. When tomatoes start to grow, they contain much less lycopene than chlorophyll, which gives them their green color. But when harvest season arrives, the days shorten and temperatures drop, causing chlorophyll to dissolve and lycopene to take over the shade of the fruit. During this time, sugar levels rise, acid levels drop, and the tomato softens. It becomes ready to eat.
