ViviGerminating seeds produce more carbon dioxide because the process of germination involves the breakdown of stored food reserves in the seed through respiration. This metabolic activity requires oxygen and generates carbon dioxide as a byproduct. Dry seeds do not undergo active metabolic processes, so they do not produce as much carbon dioxide.

What do plants produce at the end of anaerobic respiration?
Plants produce ethanol at the end of anaerobic respiration, also known as fermentation. This process helps plants generate energy in the absence of oxygen by breaking down sugars into ethanol and carbon dioxide.
What gas is being taken up when the marker on the inside arm of a respirometer moves toward a tube that contains germinating seeds?
Oxygen is being taken up by the germinating seeds in the respirometer. As the seeds undergo cellular respiration, they consume oxygen and release carbon dioxide, causing the volume of gas in the respirometer to decrease and the marker to move.
The effect of germination versus nongermination on pea seed respiration?
During germination, a seed's respiration rate increases as it activates metabolic processes to support growth. In contrast, non-germinating seeds have a lower respiration rate as they are in a dormant state. As germination progresses, the respiration rate of the seed will continue to rise to meet the demands of growth.
What two things do plants produce?
Plants produce oxygen during photosynthesis, using sunlight to convert carbon dioxide and water into glucose. They also produce fruits, which contain seeds for reproduction and dispersion.
Why are germinating seeds?
Because to stay alive
