Because its like nothing.
germinating

i think the glucose is the left over energy from when it had been germinating! :)
The beads don't go through cellular respiration so the amount of CO2 consumed is zero compared to the germinating peas whos CO2 intake is much higher because they are going through cell respiration.
The differences in photosynthesis and respiration in germinating and non-germinating peas may help us explain the adaptations plants have made to be successful organisms. Many plants generate seeds to produce their offspring and within these seeds is the genetic information they need to become mature, reproductive plants. Ten non-germinating peas were weighed, then placed in a sealed bottle and the concentration of CO2 was monitored for a period of ten to twenty minutes. This time was equally divided between light and darkness and was long enough to derive an accurate slope, and consequently photosynthesis and respiration rates, from changes in CO2 concentration. Then ten germinating peas were measured, using the same procedure. A total of two runs for germinating peas and a total of two runs for non-germinating peas were completed for this experiment. The rates derived from these procedures were then divided by its groups corresponding mass. This standardized results so that quantitatively the data was equivalent among trials and not skewed by differences in mass.
Like most organisms, when a pea is germinating, or growing, it needs more energy. As such, the respiration increases significantly during this time.

Yes. Pea and bean seeds may even begin germinating during the experiment. Main concepts All cells (plants and animals) perform cellular respiration to maintain homeostasis and grow.
Carbon Dioxide is given off because they are both like humans, needing more oxygan than carbon dioxide.
Some people have digestive difficulties with peas. Green peas give people more problems than black-eyed peas or split peas (green lentils) because green peas are higher in starch and natural sugars. Generally, yes, peas are digested.
Beans are higher in fiber and iron. Peas are still good for you, but generally higher in sugar, not a great source of fiber, and don't have that much iron.
