Question

CO2 is released during respiration after setting up the experiment what difference did you observe in colour water in tube​

Answer 1

Answer:

water level rises up in the bent tube.

Explanation:

The rise in the level of water indicates that CO2 is produced by germinating seeds during respiration. Actually the germinating seeds respire and produce CO2 which is absorbed by KOH solution. This creates a vaccum in the conical flask. The air present in the bent glass tube moves into the conical flask.This pulls the water in the bent tube further up.
