Question

13. Raw green tomatoes turns
red due to breakdown of
chlorophyll and synthesis of
O glucose
O
sugar
O fructose
O lycopene​

Answer 1

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.

Answer 2

Answer:

Conversion of green tomatoes into red occurs mainly due to the formation of chromoplasts from chloroplasts.

The chlorophyll-containing chloroplasts mature into chromoplasts (red pigment) in tomato.

The chromoplasts of such red coloured fruits contain the pigment called lycopene, which is present in the form of crystals within the lumina of membrane sacs.

They are derived from the inner membrane when the chloroplast gets matured during the process of ripening.

So, the correct answer is 'Formation of chromoplasts from chloroplasts
