Question

A kidney bean was soaked until it was soft. The seed coat was removed and the seed was split open as shown in the diagram. Both halves, P and Q, were placed on damp cotton wool and left aside for a few days. The halves were then observed. Which of the following is the possible observation?

• A. A seedling emerged from P but not from Q.
• B. Nothing happened to both P and Q.
• C. Q shrivelled up and turned brown while P remained the same.
• D. A large seedling grew first from P than from Q.

Answer 1

The correct option is A A seedling emerged from P but not from Q.

It is clearly evident from the image that part P has the embryo intact to the cotyledon, so the seedling (baby plant) can emerge only from part P of the kidney bean.

So, the correct answer is, 'A seedling emerged from P but not from Q.'
