Question

Choose the odd one out of the following terms given and name the category to which others belong:

Xylem removal, water transport, wilting, beaker of water, swelling.

Answer 1

Explanation :

1. The correct answer is swelling.
2. Swelling is commonly observed in girdling experiments above the ring.

Explanation for the other phrases:

1. To prove that water moves through the xylem, two shoots are taken.
2. In one shoot, a long ring of bark is removed keeping the xylem intact while in the other shoot, a portion of the xylem is removed.
3. Both the shoots are dipped in beakers containing water.
4. After 1-2 days, it is observed that the shoot where the xylem was removed has wilted while the other shoot shows no such observation.
5. This proved that the xylem conducts the movement of water.

Hence, the odd one out is swelling. The remaining phrases are related to the experiment which proves that water movement occurs through the xylem.
