Detailed explanation-1: -They are produced by chloroplast or by leucoplast. The chromoplasts are the one that helps in pollination and fruit dispersal. The change of tomatoes colour from photosynthetic green to red in the process of fruit ripening is because of the conversion of green colour chloroplasts to red coloured chromoplasts.
Detailed explanation-2: -Ripening and color development in tomatoes is governed primarily by two factors: temperature and the presence of a naturally occurring hormone called “ethylene.” The optimum temperature range for ripening mature green tomatoes is 68–77 deg. F.
Detailed explanation-3: -The tomato changed colour from green to red due to the breakdown of chlorophyll (present in plastids called chloroplasts) to form red carotenoids (present in plastids called chromoplasts).
Detailed explanation-4: -The red color of tomato and chilly is due to lycopene in the chloroplast. It is a bright red carotene and carotenoid pigment found in other red fruits and vegetables, such as red carrots, watermelons and papayas.
