Question

In Experiment to show the utilization of oxygen in respiration, why does water level rise in the flask with germinating seeds but not in dead seeds?

Answer 1

it's because dead seeds won't respite and thus the vaccum will not be created in the flask ..so water level will not rise ..

Answer 2

Germinating seeds respire, giving rise to CO2
which gets absorped by KOH solution creating a partial vaccum which makes the water in the tube rise up
The dead seeds do not respire and hence nothing is observed
