An experimental set-up to demonstrate respiration in germinating seeds is shown here. It is observed that water from the beaker has not risen into the delivery tube (bent tube). This is because :(1) the set-up is airtight(2) the beaker has coloured water(3) carbon dioxide is not being absorbed(4) no oxygen is available to seeds for respiration
