What is compensation point when does it occur?
The compensation point is reached during early mornings and late evenings. Respiration is relatively constant, whereas photosynthesis depends on the intensity of sunlight. When the rate of photosynthesis equals the rate of respiration or photorespiration, the compensation point occurs.
What does compensation point mean?
The compensation point refers to the situation when there is no net exchange of gas between plant or environment. In other words, photosynthetic uptake of carbon dioxide is exactly balanced by respiratory output of carbon dioxide. Thus, there is no net photosynthetic gain.
What happens in compensation point?
The compensation point is where light intensity is at the point where the rate of photosynthesis is equal to the rate of respiration. At light intensities below this point, more respiration occurs. At higher light intensities, more photosynthesis occurs.
How might you limit one of the processes in order to achieve a compensation point?
How might you limit one of the processes in order to achieve a compensation point? In order for gas exchange to not exist you would need to stop the reaction of pyruvate becoming acetyl CoA since that produces gas.
Why should we avoid resting under tree at night?
It is said that we should avoid sleeping under the tree at night, since plants carry out respiration at night and give out carbon dioxide, which is harmful for us. During the day, carbon dioxide is used by the plants for photosynthesis and hence no carbon dioxide is released.
What is compensation point class 10th?
Class 10th. Answer : The compensation point is the amount of light on the light curve where the rate of photosynthesis exactly matches the rate of respiration.
What gets reduced in photosynthesis?
Photosynthesis involves oxidation and reduction by oxidizing the oxygen in water and reducing the carbon in carbon dioxide.
Can plants grow at compensation point?
There is a light intensity at which respiration and photosynthesis cancel each other out. This is called the compensation point. Below this level carbohydrates are used up and the plant cannot grow.
What is the compensation point and why is this important to know for living organisms?
The compensation point is reached when the gross productivity of a producer is equal to the amount it must consume in respiration to stay alive. At the compensation point the net productivity is zero, and no growth can occur. Each bottle represents the net productivity of the algae at a different depth.
What is compensation point in short?
: the light intensity at which the amount of carbon dioxide released in respiration equals the amount used in photosynthesis and the amount of oxygen used in respiration equals the amount released in photosynthesis, varying in different species of plants and in response to changes in temperature and other environmental …
What is the light compensation point and what happens at this point?
The light intensity at which the net amount of oxygen produced is exactly zero, is called the compensation point for light. At this point the consumption of oxygen by the plant due to cellular respiration is equal to the rate at which oxygen is produced by photosynthesis.
What is compensation point in Lake?
The compensation point, the depth where photosynthesis equals respiration can be estimated by multiplying the Secchi disk depth by about two.
