How does germination affect respiration rates?

How does germination affect respiration rates?

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. Additionally, that at higher temperatures, the rate of cellular respiration in the seeds will increase.

Do peas undergo cellular respiration during germination?

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.

Why do germinating peas respire more?

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. Vacuum flask – to prevent heat loss from the container.

Why do germinating seeds respire?

In order for seeds to acquire the necessary energy to develop and grow, germinating seeds undergo cellular respiration. Hence, there is a high rate of consumption of oxygen in seeds that are germinating as they are living and need extra oxygen to grow.

How does the respiration rate of germinating peas compare with the respiration rate of Nongerminating peas?

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 seeds have to use respiration?

Germinating seeds are used in the experiment because germinating plants respire a lot more than a plant that has already grown, this is because the new plants require more energy and oxygen to get started. This hypothesis was not supported in the data recorded, and the colder respirometers consumed more oxygen.

What type of respiration takes place in germinating seeds?

The type of respiration taking place in moist germinating seeds is aerobic respiration. The word “aerobic” means with air. This type of respiration requires oxygen.

What is the result of respiration?

During aerobic cellular respiration, glucose reacts with oxygen, forming ATP that can be used by the cell. Carbon dioxide and water are created as byproducts. In cellular respiration, glucose and oxygen react to form ATP. Water and carbon dioxide are released as byproducts.

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.

Why do soaked peas respire more?

Because all seeds require water for germination, seeds soaked over night or for a few hours before class typically have higher respiration rates. Pea and bean seeds may even begin germinating during the experiment.

Why do germinating peas respire faster?

Why is the amount of cellular respiration is greater in germinating seeds?

In the germinating seed, cellular respiration is greater. This is because when the seed is in the dormant stage, it utilizes all the calories for surviving, and as it starts germinating, the energy demand increases that are essential for the plant’s growth.

Do germinating peas have higher rate of cellular respiration?

The rate of respiration in germinating peas was compared to the rate of the non-geminating peas. These peas were placed in two different temperatures: 10ºC and 23ºC. The hypothesis of this lab states that if the peas are germinated then the rate of cellular respiration will be higher in both room temperature and cold temperature.

What is the difference between germinating and 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.

What is the purpose of the respiration lab in peas?

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. The peas are placed in a repirometer in order to measure their oxygen consumption.

How to use A respirometer to germinate peas?

Place the germinating peas in one respirometer, while placing the non-germinating peas with glass beads in another. 6. Place only glass beads in the control respirometer. 7. Fill a large container with enough water to fully submerge the entire length of the repirometer. 8. Place one large piece of tape 3/4 of the way up the container. 9.
