Do germinating or non germinating peas consume more oxygen

The results of this lab show that the germinating peas had consumed more oxygen at a faster rate than the non-germinating peas and the beads had. The non-germinating peas and the beads showed to consume barely any oxygen at all.

Which uses more oxygen germinating peas or dormant peas?

Germinating peas consume more oxygen because they are growing and are more active than non-germinating peas.

Why did the germinating seeds consume more oxygen than the 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.

Which pea type germinating or non-germinating consumed the most oxygen Why?

Germinating peas consume the most oxygen because they are active, unlike the nongerminating peas which are dormant/inactive. Since the germinating peas are active they need a lot of oxygen to continue doing cellular respiration.

Why do non-germinating peas respire less?

In non-germinating peas, they aren’t going through mitosis and therefore don’t need as much ATP, so their rate of cellular respiration is much less.

Why do germinating peas produce more co2?

As oxygen is consumed to provide energy, germinating seeds release carbon dioxide.

What is the main difference between germinating seeds and non-germinating seeds?

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. Non-germinating seeds, however, are dormant and use very little respiration.

Do bean seeds respire faster than pea seeds?

Mung beans will respire more than an equal number of germinating peas. … The germinating peas do, in fact, respire more than germinating mung beans.

Why do germinating seeds use more oxygen?

Oxygen. Seeds need oxygen so that they can produce energy for germination and growth. The embryo gets energy by breaking down its food stores. Like all organisms, this is done through a process known as aerobic respiration.

Why do germinating peas undergo cell respiration?

During germination, a pea plant is growing, meaning its cells are actively dividing. … The pea plant cells depend on cellular respiration to furnish them with the energy they need to stay alive and grow.

Do non-germinating peas produce 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.

Why do germinating soybeans have higher oxygen consumption?

Explanation: Tube B saw the greatest amount of change in volume, this it must have had the seeds that were growing (germinating) and thus needed more energy. To create more energy the seeds used more oxygen than the other two tubes.

Are non-germinating peas alive?

The non-germinating peas consumed far less oxygen than the germinating peas. This is because, though germinating and non-germinating peas are both alive, germinating peas require a larger amount of oxygen to be consumed so that the seed will continue to grow and survive.

Why do germinating peas respire more at room temperature?

At higher temperatures, germinating peas respire faster than at lower temperatures. Cellular respiration depends on catalysts called enzymes which work more efficiently at an optimal temperature range. Also molecules generally move faster at higher temperatures, therefore allowing the reaction occur more quickly.

What is the difference between germinating and dormant peas?

Dormant peas do not have favorable environmental conditions, therefore they only need enough ATP to carry out normal processes. Germinating peas are actively growing and would require additional ATP, resulting in a higher rate of cellular respiration.

Does germination have an effect on respiration?

The seed will use those calories to survive during dormancy and to germinate. To fulfill the high-energy needs of a germinating seedling, cellular respiration increases as a seed emerges from dormancy and begins germinating.

Why seed germination is important?

Seed germination determines continuous plant production necessary for human survival with regards to the supply of medicinal plants, feed for animal grazing, and food security. The propagation of some plants is only possible by seed, and if they are difficult to germinate, this threatens their continuous existence.

Does the type of organism affect respiration rate?

If the organism is smaller and stationary (i.e. germinating peas), the rate of respiration is lower, because the organisms require less energy, as they are stationary and have less complex body functions.

What are the factors affecting seed germination?

Environmental factors such as temperature, light, pH, and soil moisture are known to affect seed germination (Chachalis and Reddy 2000; Taylorson 1987). Burial depth of seed also affects seed germination and seedling emer- gence. Weed seedlings may emerge from the soil surface to 15 cm deep (Bello et al.

Do germinating peas release carbon dioxide?

It is known that pea seeds undergo cell respiration during germination. … Using the CO2 Gas Sensor, you will monitor the carbon dioxide produced by pea seeds during cell respiration. Both germinated and non-germinated peas will be tested.

Will dry peas or germinating peas undergo cellular respiration?

Often, this energy is used to convert ADP and phosphate into ATP. Peas undergo cell respiration during germination.

How do seeds take in oxygen?

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. … The oxygen comes from tiny pockets of air in the soil.

Do seeds need oxygen in storage?

Seeds do require oxygen when moist as they are then respiring. Research is ongoing to discover the critical moisture level for anoxia storage.

Do plants need oxygen?

The two primary reasons plants need is air to photosynthesize (make food) and to breathe. Plants need to breathe for the same reason people and animals must breathe – they need oxygen to convert food into energy. The relationship between air and indoor plants is crucial to keeping your plants looking their best.

What is non germination?

If the soil became too dry, wet, cold or hot, even for a very short period, the seeds may not germinate. … Other factors in non-germinating seeds include pests, diseases and acidic soils. Wireworms in the soil may infest and eat the seeds before they can germinate.

Do seeds perform cellular respiration?

Some seeds have been soaking in water. When plants use sugars stored in their leaves or seeds they undergo cellular respiration. … As the seeds respire, they are taking in oxygen and respiring out carbon dioxide, but the carbon dioxide is being absorbed by the calcium hydroxide.

Do germinating seeds respire anaerobically?

germinating seeds respire anaerobically. During this process, no carbon dioxide is released. … The aerobic respiration takes a longer time and hence, the cells resort to anaerobic respiration.

What environmental factors affect the respiration rates of germinating beans?

The eight environmental factors effecting the rate of respiration are: (1) Oxygen Content of the Atmosphere (2) Effect of Temperature (3) Effect of Light (4) Effect of Water Contents (5) Effect of Respirable Material (6) Effect of Carbon Dioxide Concentration (7) Protoplasmic Conditions and (8) Other Factors.

What is the difference between aerobic and anaerobic respiration?

Cellular respiration that proceeds in the absence of oxygen is anaerobic respiration. Cellular respiration that proceeds in the presence of oxygen is aerobic respiration.

What is the advantage of cellular respiration?

A major advantage of aerobic respiration is the amount of energy it releases. Without oxygen, organisms can just split glucose into two molecules of pyruvate. This releases only enough energy to make two ATP molecules. With oxygen, organisms can break down glucose all the way to carbon dioxide.
