Question

The plant with variegated leaves has the starch removed from its leaves by placing it in a dark cupboard for 48 hours. Black paper is then fixed on one leaf as shown and the plant is exposed to light. After 24 hours, which part of the leaf contains starch?

1.A
2.B
3.C
4.D

Answer 1

Answer:

D

Explanation:

There is no photosynthesis in the non-green regions so not in A.

As the plant is kept in a dark room the starch in region B and C is used up and due to the paper's presence sunlight does not fall there that results in no photosynthesis too.

Thus the only region left is D
