Swati took a white carnation flower and split its stalk halfway along the length and arranged a set up as shown in the given figure. What will she observe after a few hours?

Options

A. Half the petals will turn blue, while the other half will remain white.
B. Half of the petals will turn red, while the other half will remain white.
C. All the petals will show a mixed shade of blue and white.
D. Half the petals will turn red, and the other half will turn blue.

Answer

D

Explanation

When the split stalk of white carnation flower is placed in two different coloured solutions, then half petals of flower would show red colour and half would show blue, because stem conducts water and minerals to leaves and food prepared by the leaves to other parts of plant through special conducting structures. So, stem part soaked in red solution would impart red colour to petals and stem part soaked in blue solution would impart blue colour.
