Question

A fruit is green when unripe but becomes beautifully coloured when ripe. How does this change occur?What is the importance of this change?

Answer 1

The change in color of the fruits on ripening is a chemical change.
It occurs due to the formation of new enzymes in the fruits.
Enzymes help in ripening of fruits.
An unripe fruit is green because it contains chloroplasts in its skin.
Towards ripening of the fruit,the chloroplasts are changed into chromoplasts which gives the fruit attractive non-green colour.

Answer 2

Answer:

The green color of the unripe fruit is due to the presence of chlorophyll, which is replaced by the synthesis of carotenoids or anthocyanins when the fruit becomes ripe.

Explanation:

Chemical Reaction in fruits

• Unripe fruits are green because of chlorophyll in the cells.
• When they ripen, the chlorophyll molecules breakdown, which is replaced by orange carotenoids and red anthocyanins.
• These are anti-oxidants that prevent the fruit from spoiling in the air.
• Ethylene gas, which is known as fruit-ripening hormone, also helps the fruit to ripen.

The importance of color change in fruits

• The color change that occurs when the fruit transforms from the unripe to ripe stage is important because this color change is the sign that helps the fruit-eating animals to consume their food.

• It is also important for the plants, which helps in the distribution of seeds as animals eat them.
