Will germinating peas have a higher respiration rate?
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.
Why do germinating peas have a higher respiration rate?
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.
Do germinating seeds respire faster?
To fulfill the high-energy needs of a germinating seedling, cellular respiration increases as a seed emerges from dormancy and begins germinating. However, seeds respire at a lower rate throughout dormancy.
Do peas undergo respiration before germination?
Peas are seeds, or embryonic plants. When they are exposed to the right conditions, the plant will emerge from the seed and begin to grow; this process is called germination. Cellular respiration is necessary for germination to occur.
Why do non-germinating peas consume less oxygen?
The non-germinating peas shows hardly any consumption of oxygen. 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.
Are the germinating or non-germinating peas doing cellular respiration the fastest?
Non-germinating peas and glass beads were also tested in the procedure, the glass beads acting as the control. Increasing the temperature could increase the oxygen consumption. Germinating peas have a higher respiration rate than non-germinating. 2.
Do germinating or non-germinating peas consume more oxygen?
Are non-germinating seeds dead?
It was also hypothesized that the germinating seeds would consume more oxygen than the non-germinating seeds because the germinating seeds are living and the non-germinating seeds are dead or not nearly as active.
Do germinating peas absorb oxygen?
Why do germinating peas produce carbon dioxide? 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-germinating 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 do non-germinating peas respire less?
The non-germinating peas shows hardly any consumption of oxygen. Since the germinating peas are germinating or sprouting, they require a more extensive amount of energy or ATP. Therefore, the non-germinating peas have a significantly low rate of respiration in comparison with the germinating peas.
Do peas take in oxygen?
Do Plants undergo cell respiration?
All cells in a plant undergo aerobic respiration, but only chlorophyll cells undergo photosynthesis. Photosynthesis provides the sugar needed by cells for aerobic respiration as well as the by-products oxygen and ATP . At the same time, each cell will undergo respiration producing carbon dioxide, water, and ATP.
Do non germinating seeds respire?
Non-germinating seeds have minimal cellular respiration as they are dormant and do not need to be metabolically active (Van Assche, et. Al,1989). Non-germinating seeds respire to stay alive, not to create energy for growth and movement; their cell respiration rate is slower, providing enough energy for survival (Van Assche, et. Al,1989).
What is seed respiration?
Seeds don’t breathe in the same way mammals do. Instead, they breathe at a cellular level. In cellular respiration, the seed uses stored sugars, water and oxygen to burn energy at a cellular level and germinate, or sprout. Respiration increases dramatically as the seed sprouts.
