Question

Which one can respire in the absence of oxygen?

• A. Seeds
• B. Leaves
• C. Stem
• D. Root

Answer 1

The correct option is A Seeds

Respiration at cellular level may be aerobic or anaerobic. When there is absence of oxygen, the respiration that occurs is called anaerobic respiration. Germinating seeds at first carry out anaerobic respiration in absence of free oxygen because of the toughness of seed coat. They use the stored material for energy and produce alcohol as byproduct.

So, the correct answer is 'Seeds'.
