Seeds require necessary energy to develop and grow, so germinating seeds undergo cellular respiration. Cellular respiration rates increase to accommodate the cell-building activities required to break open the seed and produce the initial root and stem structures.
Why do plants undergo cellular respiration?
Respiration is essential for growth and maintenance of all plant tissues, and plays an important role in the carbon balance of individual cells, whole-plants and ecosystems, as well as in the global carbon cycle.
Why do non germinating seeds undergo cellular respiration?
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.
Why do peas need to undergo cellular respiration?
Germinating peas undergo cell respiration in order to supply the energy they need to grow and develop. Cell respiration is the process by which sugars are broken down to release energy. The respired sugars are stored in structures called cotyledons in the pea seed.
Why is cellular respiration important for germinating seeds Related Questions
How do seeds use cellular respiration?
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. The seed continues to breathe until the plant can make its own food via the process of photosynthesis.
What type of respiration is germinating seeds?
During the respiration of germinating seeds, oxygen is taken in, while carbon dioxide (CO2) is released back, and this phenomenon has been experimentally proved. This mode of respiration corresponds to aerobic respiration.
When and why would plants choose to use cellular respiration instead of photosynthesis?
The plant requires cellular respiration in order to release the bound chemical energy in the glucose and make ATP for the use of metabolic activities of the cell. Cellular respiration requires carbohydrates and oxygen. Hence, plants need to have the ability to find oxygen and carbohydrates.
Why is cellular respiration important?
What is the purpose of cellular respiration? Cellular respiration is used to generate usable ATP energy in order to support many other reactions in the body. ATP is particularly important for energetically unfavorable reactions that would otherwise not occur without an energy input.
What is the relevance of photosynthesis and cellular respiration to seed germination and plant growth?
The glucose formed during photosynthesis provides energy to the plants. The process of respiration makes effective use of energy. In this process, oxygen is given off by the plants to the surroundings. The carbon dioxide is taken up from the surroundings in used in photosynthesis.
Do germinating seeds respire more?
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 germinating seeds respire more than non germinating seeds?
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 seeds consume more 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. —a series of reactions where energy is released from glucose, using oxygen.
Why do germinating peas respire more than worms?
The germinating peas, which are still growing and preparing for reproduction, need a lot of energy in order to do this, and so they will have a high rate of oxygen consumption as they must undergo cellular respiration quickly in order to provide their growing cells with energy in the form of ATP.
Is cellular respiration necessary for a plant to grow and reproduce?
Today, most organisms on land, freshwater and the oceans, including plants, use cellular respiration to extract the energy they need to function, grow, and reproduce.
What do seeds release during cellular respiration?
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.
How do germinating seeds respire anaerobically?
As you can imagine, seed germination is a large energy-driven process. So to compensate for lack of oxygen, germinating seeds adapt anaerobic respiration. This kind of respiration is conditioned predominantly by the internal factors of the seed, and thus no external oxygen is needed.
Do germinating seeds undergo photosynthesis?
During germination, photosynthesis does not occur because the organelles responsible for this process to take place are not present until the seed develops into a young seedling.
How do germinating seeds release energy?
Seeds respire and release energy during the germination process. Heat is produced during the respiration process.
What type of cellular respiration do plants use?
While the molecules are being reorganized, carbon dioxide is formed and electrons are removed and placed into an electron transport system which (like in photosynthesis) produces a lot of ATP for the plant to use for growth and reproduction. This stage (aerobic respiration) does need oxygen.
Can plants do cellular respiration without photosynthesis?
Both cellular respiration and photosynthesis are parts of a mutually beneficial relationship. Photosynthesis cannot occur without cellular respiration and cellular respiration certainly cannot occur without photosynthesis.
