What happens at the compensation point?
The Compensation Point is the point at which Photosynthesis and Respiration are in balance, so (in a perfect world) the amount of oxygen being produced by photosynthesis will just balance the amount being used by respiration. At this point there will be NO oxygen bubbles being produced in the leaf discs.
What is light compensation level?
compensation level The depth at which light penetration in aquatic ecosystems is so reduced that oxygen production by photosynthesis just balances oxygen consumption by respiration. Generally this implies a light intensity of about 1 per cent of full daylight.
What is meant by compensation point in biology?
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 are the light compensation and light saturation points?
This point where the light intensity does not increase the photosynthesis rate is called the light saturation point. When this point is reached, the photosynthesis rate curve becomes flat (Figure 1). Figure 1. Graph of the light compensation point and the light saturation point.
What is compensation point of photosynthesis Class 10?
Answer: When the rate of photosynthesis is equal to rate of respiration, it is called as compensation point. The rate of liberation of O3 during photosynthesis is equal to the rate of liberation of CO2 during respiration. Thus, there is no net uptake of gases from the environment.
What is light saturation point?
(The light saturation point is the intensity at which additional increases in light do not increase photo- synthesis.) This means the value of supplemental lighting is marginalized at a low CO2 concentration.
Why is compensation point important?
The compensation point (Ic) is the irradiance at which photosynthesis equals respiration. It is a useful estimate of the lowest irradiance at which algae can maintain an autotrophic existence.
What affects light compensation point?
The compensation depth between photosynthesis and respiration of phytoplankton in the ocean must be dependent on some factors: the illumination at the surface, the transparency of the water, the biological character of the plankton present, and the temperature.
What is the light compensation point quizlet?
1- The point at which the carbon dioxide output is maximized. 2- The point at which additional light does not lead to increased photosynthesis.
What is compensation point Class 10?
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 is compensation point Class 8?
The amount of light intensity on the light curve where the rate of respiration is equal to the rate of photosynthesis is called compensation point.
What is compensation point in plant?
compensation point The point reached in a plant when the rate of photosynthesis is equal to the rate of respiration. This means that the carbon dioxide released from respiration is equivalent to that which is taken up during photosynthesis. The compensation point is reached as light intensity increases.
