Question

Tomatoes are red because of the presence
(1) Chloroplast
(2) Chromoplasts
(3) Leucoplasts
(4) Chromatin​

Answer 1

Required Answer :-

• 3. Leucoplasts

Explanation :-

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.

Lycopene and b-carotene are major pigments in ripe tomatoes, the former being responsible for the red color. In yellow ripe fruit, lycopene concentration was 99.3% less than that present in red fruits (Table III).
