Question

What can we infer from three bean experiment?

• A. Seeds require only air and suitable temperature for germination
• B. Seeds require only water and suitable temperature for germination
• C. Seeds require both air and water along with suitable temperature for germination
• D. Seeds only require soil for germination.

Answer 1

The correct option is C

Seeds require both air and water along with suitable temperature for germination

From the three bean seeds experiment, we can observe that seeds require water, air and suitable temperature to germinate.
The experiment starts with tying three seeds on a glass slide and is kept in a beaker containing water in such a way that one seed is completely immersed in water, the middle one is half immersed and the last one is in the air. After a few days, we observe that middle seed has germinated as it gets all three necessary conditions.
