Why do germinating peas respire more?

The germinating seeds will have a higher rate of oxygen consumption than the non-germinating seeds because the germinating seeds are living and need extra oxygen so that they can grow, whereas the non-germinating seeds are not nearly as active and won’t respire as much.

In addition to the germinating peas, the nongerminating peas, are not germinating so because of this they do not need significant amount of ATP production. Therefore, the nongerminating peas have a significantly low rate of respiration in comparison with the germinating peas.

Additionally, what happens to the rate of oxygen consumed by germinating peas? The non-germinating peas consumed far less oxygen than the germinating pea. During respiration, oxygen will be consumed and its volume will be reduced to solid. The result was a decrease in gas volume within the tube, and a related decrease in pressure in the tube.

Beside above, do germinating or non germinating peas consume more oxygen?

The nongerminating peas however, did not consume much oxygen at all. Since the germinating peas are germinating, they require more extensive and readily available energy or ATP. Thus they have high oxygen consumption rates or respiration rates for oxidative phosphorylation.

What does germinating peas mean?

More Information on Germinating Peas Seeds contain a plant embryo and its initial food supply protected by a seed coat. When warmth and moisture conditions are favorable, germination, or sprouting, will begin. When you soak pea seeds for this laboratory, germination begins.

Do non germinating peas respire?

Non-germinating seeds, however, are dormant and use very little respiration. Some respiration must occur in order for the seed to live. The rate of cellular respiration will be greater in germinating peas than in dry peas, and temperature will have a direct effect on this rate.

Why does cellular respiration increase with temperature?

The increase in temperature enhances the rate of cellular respiration. It is due to the heat speeds up the reactions, means the kinetic energy is higher. It means reactions speed up and rate of cellular respiration increases. When temperature decreases, in order to conserve energy, cellular processes slow.

Why is it important to use germinated seeds without leaves?

Why was it important to use germinated seeds without leaves for this experiment? Because if the seeds had leaves the reaction between the NaOH and the CO2 would be messed up by the leaves which would alter the oxygen levels in the tube.

How do peas respire?

The germinating peas will produce the most heat. Peas will carry out respiration to release the energy needed for growth and heat energy is produced as it is an exothermic reaction. The peas are also covered in microbes which also respire producing heat.

How does temperature affect cellular respiration in peas?

The effect of temperature on the rate of cell respiration in the peas is that the higher the temperature, the higher the rate of cell respiration because the cool water causes the enzymes to slow down, causing the reactions of cellular respiration to slow down, and therefore the rate of respiration to be slower.

How does body size affect the rate of respiration?

Respiration should generally increase with body mass, as larger organisms need more energy; thus, b is usually positive but is commonly less then 1, meaning that while larger animals use overall more oxygen per individual than small animals they use less oxygen per unit body mass.

How does a simple Respirometer work?

How the Respirometer Works. When the tip of the respirometer is submerged, no additional air will enter. As O2 is used up, the pressure of gases inside the respirometer decreases. Notice that as the gas volume inside the vial decreases, the pressure of water outside the vial forces water into the pipette.

How do you measure respiratory rate?

Respirometer. A respirometer is a device used to measure the rate of respiration of a living organism by measuring its rate of exchange of oxygen and/or carbon dioxide. They allow investigation into how factors such as age, or chemicals affect the rate of respiration.

Why do germinating peas produce carbon dioxide?

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 are taking in oxygen and respiring out carbon dioxide, but the carbon dioxide is absorbed by the calcium hydroxide.

Do non germinated seeds consume oxygen?

The germinating seeds will have a higher rate of oxygen consumption than the non-germinating seeds because the germinating seeds are living and need extra oxygen so that they can grow, whereas the non-germinating seeds are not nearly as active and won’t respire as much.

Why would there be a relationship between temperature and oxygen consumption?

In the process of coal heating and oxidation, the oxygen consumption rate increases with temperature rise; before the critical temperature (about 150 °C) oxygen consumption rate increases slowly, however, it increases rapidly when the coal temperature surpasses the critical temperature.

What do you mean by germination?

Germination is the process by which an organism grows from a seed or similar structure. The most common example of germination is the sprouting of a seedling from a seed of an angiosperm or gymnosperm.

Why do dormant seeds respire?

Why do dormant seeds respire? To fulfill the high-energy needs of a germinating seedling, cellular respirationincreases as a seed emerges from dormancy and begins germinating. As theseeds respire, they are taking in oxygen and respiring out carbon dioxide, but the carbon dioxide is absorbed by the calcium hydroxide.

What is the purpose of Koh?

What is the purpose of KOH in this experiment? KOH removes carbon dioxide formed during cellular respiration.
