Question

Which of the following statements are true about the given experimental setup?

• A. Emergence of tiny radical in seeds in A.
• B. Seeds in B will not germinate at all.
• C. Seeds in C will successfully germinate .
• D. Seeds in B will stop germinating after emergence of a tiny radical.

Answer 1

Answer: (C), (D)

Seeds in B will stop germinating after emergence of a tiny radical.

Oxygen and water are needed for germination.
Seeds in A lack water and will not germinate.
Seeds in B have water as cotton is moist but has limited oxygen. So, they will stop germinating after the emergence of a tiny radical.
Seeds in C have oxygen as well as water and will germinate successfully.
