Question

Take a beaker and fill half of it with water. Put some wheat seeds in it, stir it and wait for some time. Which of the following holds true regarding the observation and inference of this experiment?

• A. Healthy seeds being lighter float on the surface of water.
• B. Damaged seeds being lighter float on the surface of water.
• C. Some healthy seeds and some damaged seeds float on the surface of water.
• D. Damaged seeds being heavier settle down at the bottom.

Answer 1

Answer: (B)

Damaged seeds being lighter float on the surface of water.

If some wheat seeds are added into a beaker half filled with water, the damaged seeds will float on the surface of water after some time. At the same time, the healthy seeds will settle down at the bottom. This is because the damaged seeds are lighter and healthy seeds are heavier.

Thus, the correct answer is 'Damaged seeds being lighter float on the surface of water..'
