Answer 1

QUESTION:-

The bluing of rose petals is due to

ANSWER:-

Option (2)

Calcium salt

EXPLANATION:-

• The petals of distinct red roses sometimes becomes bluish at a later stage of flowering and blooming. This phenomenon is called "bluing effect of rose"

• The results of researchers show that the calcium localises within the epidermis of the rose petals which makes salt and is weakly bounded with tannic substances within the rose petal. It is the reason behind making the epidermis layer rigid.

• The change in pH occurs in the rose petal due to an increase in calcium salt which is the main cause of the bluing effect.

• Other reasons for the bluing effect of rose are the decrease in water content and increase in ion leakage of the petal cells.
