What would you expect to happen to the respiratory rate if the peas were submerged in a cold water bath instead of a room temperature bath Why?

The rate of cellular respiration will be higher in germinating peas in cold and room temperature water baths than in that of the beads or non-germinating peas. The cooler temperature in the cold water baths should slow the process of cellular respiration in the peas.

How do you measure the rate of respiration in germinating seeds?

In this exercise, a respirometer will be used to measure oxygen consumption. The instrument contains limewater and germinating seeds. As the seeds consume oxygen, carbon dioxide is excreted. The carbon dioxide is then absorbed by the limewater, creating a slight vacuum in the respirometer.

Why would you expect the volume of gas to decrease in the respirometer as the experiment progresses?

In the experiment water will move toward the region of lower pressure. The result is a decrease in gas volume within the tube, and a related decrease in pressure in the tube. The respirometer with just the glass beads will allow changes in volume due to changes in atmospheric pressure or temperature changes.

How do the respiratory rates for germinating and Nongerminating peas compare?

This lab showed that cellular respiration rates are greater in germinating peas than in non-germinating peas. It also showed that respiration rates increase as temperature increases. The non-germinating peas showed very little oxygen consumption while the germinating peas had a high rate of oxygen consumption.

How do germinating peas undergo cell respiration?

Cellular respiration rate is slower at colder temperature. Why do germinating peas undergo cell respiration? They are growing at a fast rate and need energy to grow, so they use cellular respiration.

Why do germinating peas undergo cell respiration?

Why do germinating peas undergo cell respiration? They are growing at a fast rate and need energy to grow, so they use cellular respiration.

Why do germinating peas undergo cell respiration quizlet?

The affect of germination on the rate of cell respiration in peas is that in peas that are germinated, the rate of cell respiration is higher because the cells are growing/going through mitosis which requires energy/ATP in order to be carried out which is generated through the process of cellular respiration.

Why the rate of respiration is higher in germinating seeds?

To fulfill the high-energy needs of a germinating seedling, cellular respiration increases as a seed emerges from dormancy and begins germinating. As the seeds respire they take in oxygen and release carbon dioxide at roughly the same rate.

What variables affect the respiration rate of seeds?

The eight environmental factors effecting the rate of respiration are: (1) Oxygen Content of the Atmosphere (2) Effect of Temperature (3) Effect of Light (4) Effect of Water Contents (5) Effect of Respirable Material (6) Effect of Carbon Dioxide Concentration (7) Protoplasmic Conditions and (8) Other Factors.

What is the effect of germination on pea seed respiration?

Why are germinating seeds used to demonstrate experiments on respiration?

Germinating seeds are used in the experiment of the release of carbon dioxide during respiration because they respire a lot more than a plant that has already grown. A new plant will require more energy and oxygen to get started.

What was the respiration rate of germinating peas?

The results showed that the germinating peas had the highest rate of respiration with a total loss of .32mL of O2 in 15 minutes, while the non-germinating peas had a lower respiration with a total loss of .19mL O2 in 15 minutes. The control group of beads did not respirate at all.

Which is faster the non germinating peas or the beads?

The non-germinating peas and the beads showed to consume barely any oxygen at all. In this lab, the germinating peas respiration rate proved to be faster than the respiration rate of non-germinating peas. Finally, this experiment showed that respiration rates increase as the temperature increases.

How are peas measured in a respiration lab?

The peas are placed in a repirometer in order to measure their oxygen consumption. The independent variable for this lab is whether the peas are germinating or not, while the dependent variable is the rate of respiration.

Why do germinating peas consume more oxygen than crickets?

This makes sense because the germinating peas consume the most energy of all the organisms and will therefore consume more oxygen for cellular respiration. The green line, the cricket at 21°C, also increases steadily but does not go as high as the blue line meaning that the cricket did not consume as much oxygen as the germinating peas.
