Change of colour from green to red during ripening of chili is due to
A. Pigments present in the vacuole
B. Transformation of chloroplast to chromoplast
C. Transformation of leucoplast to chloroplast
D. Phycoerythrin pigments found in chloroplast
Solution
In general, the unripe habaneros are green in colour, but their colour varies as they grow, ranging from orange, red , white, yellow, green and purple. The ripening requires both shifts in fruit colour and texture.
Complete Answer:
Chlorophylls are the pigments before the chilis mature (ripen). Chlorophyll development stops when ripening is activated (by enzyme signals), either due to seed maturation or nutrient cut-off, and chili produces carotenoid pigments, as well as sugars and vitamins A , C and E.A chilli has optimum heat when it is full size and green. It's just as hot when it's red, but it's sweeter, like the difference between a green pepper and a red pepper.
The change in colour of chilli from green to red is due to the conversion of chloroplast to chromoplast because chloroplast is green in colour at the immature stage whereas the chloroplast disappears at maturation and carotenoid-containing chromoplast imparts red colour.

The correct Answer is option (B) Transformation of chloroplast to chromoplast.
Note: Eating them raw is the perfect way to eat both red and green chilli. This will help you get rid of any issues associated with synthetic colours in the powder being adulterated and mixed. You can store them in the refrigerator whenever you buy them, which will help them stay fresh.
