Question

Beetroot is pinkish-red in colour which is due to
A)Chlorophyll
B)Betanin
C)Carotenoids
D)Haemocyanin

Answer 1

Hint: The coloration in the beetroot is due to the presence of a water-soluble red pigment acknowledged as betacyanin. The pigment is placed in the mobile vacuole not in the chloroplast. The betacyanin pigment only loses its colour when in warm water due to denaturation of plasma membrane whereas in cold water the plasma membrane remains intact, so no colour is released.

Complete answer:
Beetroot carries the pigment anthocyanin. The mobile vacuole in fruits and plants is where it can be found. In intense temperatures it plays a protecting function to the plants. The anthocyanin is capable of taking in light in the blue- green wavelengths and it permits the red wavelengths to be scattered through the plant tissues and make these organs visible to us as red. They are naturally going on pigment which is common in all the human food plan and a favourable one too.

Now let us find solution from given options:
Chlorophyll : It is usually greenish in colour and it is present in the leaves of the plants.
Betanin : It is usually pinkish and reddish in colour and it is present in many vegetables including beetroot.
Carotenoids : They are usually yellow orange in colour and are present in leaves of plants.
Haemocyanin : It is the blood pigment of earthworms and many other annelids and is usually white in colour

Note: The disintegration of plasma membrane can result in leaking of colour. Because the pigment existing in the vacuole is included through a membrane single layer referred to as tonoplast receives destruction due to non- functioning of membrane proteins and their shape receives desiccated too.
