Question

in the experiment of respiration why germinating seeds are used??

Answer 1

To fulfill the high-energy needs of a germinating seedling, cellular respiration increases as a seed emerges from dormancy and begins germinating. ... As theseeds respire, they are taking in oxygen and respiring out carbon dioxide, but the carbon dioxide is absorbed by the calcium hydroxide.

Answer 2

The rate of respiration of germinating and non-germinating peas in this experiment was determined by the consumption of oxygen. Potassium Hydroxide (KOH) was used to alter the equilibrium. KOH removed the carbon dioxide and oxygen was used by cellular respiration thus decreasing the gas in the respirometer.
