What organelle in plants causes tomatoes turning red?
Lycopene is responsible for the red color of a ripe fruit in the cultivated tomato, while the yellow color of the flowers is due to xanthophylls violaxanthin and neoxanthin. Carotenoid biosynthesis occurs in both chromoplasts and chloroplasts.
Do tomatoes go from green to yellow to red?
From green to yellow or red

lactic acid
The real acidity of milk is due to lactic acid. This is never found in milk when it is first drawn from the udder. It is produced by the action of the lactic acid organisms on the milk sugar. The so-called apparent acidity of milk is what gives fresh milk its acid reaction.

Pigments in Climacteric and Non-climateric Fruits
| Fruits | Pigment class | Typical colors |
|---|---|---|
| Climacteric | Chlorophyll | Green |
| Carotenoid | Orange, yellow, pink, red | |
| Anthocyanin | Purple, red | |
| Non-climacteric | Chlorophyll | Green |
Why is the colour of tomato green at first and then changes to red?
As the tomato ripens, its colour starts 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 can easily be seen as the dominant colour of the tomato, ie red.
Why do green tomatoes turn red?
Explanation: Chromoplasts are formed from either chloroplasts or leucoplasts. Chromoplasts contain carotenoid pigments. Green tomatoes turn red due to the transformation of chloroplasts to chromoplasts. Chlorophyll degrades and carotenoid pigments aggregate as they mature.
