why do germinating peas respire more

by Kathleen O'Kon Published 4 years ago Updated 3 years ago

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.

Germinating peas grow rapidly. This growth process requires a lot of energy for cell division, so the rate of respiration in germinating peas is high. One way to measure the rate of respiration is to measure the heat produced in the process.

Do germinating or non-germinating peas consume more oxygen?

Germinating pea seeds require more energy to grow which allow them to have a high rate of respiration to take in more oxygen compared to a non-germinating pea seed, which is dormant. Generally, germinating seeds consumes more oxygen than beads or non-germinating beads alone because it is actively growing.

Why do non germinating peas respire less?

  • Place 25 germinating peas in the respirometer vial (s) 1.
  • Place 25 dry peas and beads in your respirometer vial (s) 2.
  • Place beads only in your respirometer vial (s) 3.

Why is temperature needed for germination?

temperature giving the greatest percentage of germination in the shortest time. The maximum temperature is governed by the temperature at which denaturation of proteins essential for germination occurs. The optimum temperature for most seeds is between 15 and 30oC. The maximum temperature for most species is between 30 and 40oC.

Why do non-germinating peas?

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

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 peas respire faster?

The rise in temperature effects the rate of respiration and since we know germinating seeds respire faster than non-germinating, also the germinating seeds at different temperature has different rate of respiration which i have shown in this experiment.

Why do germinating peas produce more carbon dioxide?

As oxygen is consumed to provide energy, germinating seeds release carbon dioxide. This carbon dioxide is absorbed by potassium carbonate and thus the overall gaseous pressure of the respirometer will be reduced.

Why the germinating seeds have a higher rate of respiration compared to non-germinating seeds?

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.

Do germinating peas undergo cellular respiration?

All organisms, including plants and animals, oxidize glucose for energy. Often, this energy is used to convert ADP and phosphate into ATP. Peas undergo cell respiration during germination.

Do bean seeds respire faster than pea seeds?

hypothesis. The germinating peas do, in fact, respire more than germinating mung beans.

Do germinating seeds respire?

Germinating seeds carry out cellular respiration processes in much the same way as plant and animal cells do. Cellular respiration takes place in three stages starting with glycolysis.
