Why do peas go through cellular respiration?
The food stored in the seed provides the pea plant cells with the energy they need to maintain themselves and divide, since the plant is not yet capturing sunlight through photosynthesis. The pea plant cells depend on cellular respiration to furnish them with the energy they need to stay alive and grow.
Why does cellular respiration occur faster in germinating peas?
Germination is the growth processes of a seed. It requires a lot of energy to break the seed coat and as it continues to grow this energy need increases. Respiration is required to access this energy so as the seed germinates its respiration rates increase.
Does cellular respiration occur in peas?
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. The germinating peas which have been disinfected will produce less heat than Flask A.
Why would germinating peas respire faster than non-germinating peas?
Since the germinating peas are germinating or sprouting, they require a more extensive amount of energy or ATP. This allows them to have high oxygen consumption rates or respiration rates in this experiment.
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.
Why should the flask not be completely filled with peas?
Ans: It is because living seeds produce heat energy. It is advisable not to fill the flasks completely with seeds.
Which of the peas used more oxygen?
The germinating peas used both more oxygen and more ATP. You just studied 10 terms!
Why do germinating peas need more oxygen?
Germinating peas consume more oxygen because they are growing and are more active than non-germinating peas.
Do boiled peas respire?
Peas are disinfected, half of which are then boiled, before inserting equal masses into two vacuum flasks. One flask records a temperature increase as the peas respire, however the other does not because boiling the peas denatured enzymes, preventing respiration.
Why does respiration decrease with temperature?
Explanation: 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. When temperature decreases, in order to conserve energy, cellular processes slow.
At which temperature did the peas consume the most oxygen?
This activity uses a number of controls. Identify at least three of the control, and describe the purpose of each control. The amount of oxygen consumed was greatest in germinating peas in warm water.
Why do boiled peas not respire?
Which is faster the respiration rate of germinating peas?
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. Concluding that temperature and respiration rates are directly proportional and have a direct relationship to each other.
Why do peas need to respirate to grow?
The purpose of this lab is to compare the respiration rates of germinating and non-germinating peas. Peas need to respirate to survive and grow. They respirate by converting glucose and oxygen into water and carbon dioxide.
Why does cellular respiration occur in room temperature peas?
Higher temperatures tend to promote energy and metabolic excitement. Based on the results of the experiment, it is safe to conclude that Cellular respiration is occurring in germinating and non-germination peas, however it occurs much faster in the highly active, room temperature, germinating peas.
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.
