why the rate of respiration is higher in germinating seeds​

Explanation:

To fulfill the high-energy needs of a germinating seedling, cellular respiration increases as a seed emerges from dormancy and begins germinating. However, seeds respire at a lower rate throughout dormancy. ... As the seeds respire they take in oxygen and release carbon dioxide at roughly the same rate.

The germination rate of the seeds are  constantly decreased by the lowering of O_{2} partial pressure, but the germination will taken place, at 0.1 kilopascal very slowly; And the "adenylate energy charge" stayed higher than of 0.6.

Explanation:

  • The differences in the "germination rates" and "adenylate energy charge values" could not be interpreted by differences in the "sensitivity of respiration to O_{2}".
  • To fulfill the more-energy require of a "germinating seedling", "cellular respiration" increases as a seed appeared from dormancy and start germinating.
  • However, seeds are respiring at a "lower rate throughout dormancy".
  • As the seeds breathe and they get in O_{2}  and deliver CO_{2} at roughly the same rate.

To know more:

In the experimental set-up to show that "the germinating seeds give out carbon dioxide", answer the following question:-

{a} Why do we keep the conical flask airtight?

{b} Name the substance kept in the small test tube inside the conical flask. Write its role.

{c} Why does water rise in the delivery tube?
