Question

(b) How do coloured or variegated leaves manufacture food? Why do they have variegated or coloured leaves?​

Answer 1

Answer:

Soak the leaves in iodine and the green parts will turn blue/black and the non green parts will stay the yellowish brown colour of iodine liquid. The green parts contain starch, which makes iodine turn blue/black. The blue/black stain is what shows starch is present.
