What is the end product of anaerobic respiration in germinating seeds?
go die
In this activity you are investigating both the effect of germination versus non germination and warm temperature versus cold temperature on respiration rate identify two hypotheses being tested?
The hypotheses being tested are the effect on the respiration rate. In this case the two are warm temperature vs. cold temperature & germinating vs. non germinating. (temperature & germination)
What gas is being taken up when the marker on the inside arm of a respirometer moves toward a tube that contains germinating seeds?
Oxygen is being taken up by the germinating seeds in the respirometer. As the seeds undergo cellular respiration, they consume oxygen and release carbon dioxide, causing the volume of gas in the respirometer to decrease and the marker to move.
How would you use a thermometer to show that germinating seeds are respiring?
respiration increases as temperature increases so you could infer that if the seeds are warmer than the surrounding evironment, then respiration is occuring.
The effect of germination versus nongermination on pea seed respiration?
During germination, a seed's respiration rate increases as it activates metabolic processes to support growth. In contrast, non-germinating seeds have a lower respiration rate as they are in a dormant state. As germination progresses, the respiration rate of the seed will continue to rise to meet the demands of growth.
Why Alkaline pyrogallol absorbs oxygen when used on germinataing seeds?
alkaline pyrogallol will still absorb oxygen with or without germinating seeds. There is a common chemistry experiment were the percentage of oxygen is determined by mixing pyrogallol and base sodium hydroxide which forms the alkaline pyrogallol. Don't ask me why and how the mechanism is still not clear to me.
What is the affect of temperature on the rate of cell respiration in peas?
this should help:Respiration slowed down when the temperature was reduced, and respiration increased when the temperature increased. The germinating pea seeds consumed the most oxygen. The vials containing the dry seeds and glass beads had the same result. When the germinating seed is cooled down however, the rate of oxygen consumption is reduced drastically because all of the cellular processes are slowed down from the cooler surroundings. The germinating seeds consumed almost no oxygen throughout the experiment in the 10-degree C water bath. In the room temperature water bath, the glass beads, and the dry pea seeds and glass beads consumed the least amount of oxygen (see chart 1). Which means that the germinating seeds would slow down their respiration rates because of the colder temperature. They consumed almost three times as much oxygen as the glass beads alone, and the glass beads and dry pea seeds.
What is the function of sucrose and calcium nitrate in the germinating solution?
Sucrose provides a source of energy for the germinating seeds through respiration, while calcium nitrate supplies calcium and nitrogen for various metabolic processes. These nutrients are essential for promoting growth and development in the germinating plants.
What modifications of cellular respiration might you expect to find in dormant seeds?
In dormant seeds, cellular respiration is typically reduced to minimal levels due to limited oxygen availability and low metabolic activity. The seeds rely predominantly on anaerobic metabolism for energy production. Once the seeds germinate and become active, cellular respiration increases to support growth and metabolic processes.
What do plants produce at the end of anaerobic respiration?
Plants produce ethanol at the end of anaerobic respiration, also known as fermentation. This process helps plants generate energy in the absence of oxygen by breaking down sugars into ethanol and carbon dioxide.
Why do germinating seeds produce more carbon dioxide than dry seeds?
Germinating seeds produce more carbon dioxide because the process of germination involves the breakdown of stored food reserves in the seed through respiration. This metabolic activity requires oxygen and generates carbon dioxide as a byproduct. Dry seeds do not undergo active metabolic processes, so they do not produce as much carbon dioxide.
Why are the seeds not germinating?
Seeds may not be germinating due to factors such as insufficient water, improper temperature, lack of light, or poor soil quality.
