What happens to a plant when the light intensity is below the light 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.
What is the compensation point in plants?
Compensation Point for Light (of photosynthetic plants) is the intensity of light at which the rate of carbon dioxide uptake (photosynthesis) is exactly balanced by the rate of carbon dioxide production (respiration) or equivalently, the light intensity at which the rate of oxygen production is exactly balanced by the …
Is the plant undergoing photosynthesis at light intensities greater than the light compensation point?
The saturation point is essentially the upper bookend for light intensity – light intensity higher than the saturation point does not increase the rate of photosynthesis. The lower bookend of light intensity is called the light compensation point.
What is the difference between the area of leaves grown in shade and grown in light?
Leaves which grow in the shade (‘shade leaves’) are generally larger in area but thinner than leaves which grow in full sunlight (‘sun leaves’). … The larger shade leaves provide a larger area for absorbing light energy for photosynthesis in a place where light levels are low.
What happens during 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 meant by term compensation point?
: 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 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 determines light compensation point?
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.
What is the meaning of compensation point in photosynthesis?
The (light) compensation point is the light intensity on the light curve where the rate of photosynthesis exactly matches the rate of cellular respiration.
What is the difference between light intensity and light quality?
Light intensity refers to the total amount of light that plant receives. In contrast to light quality, description of the intensity of light does not consider wavelength or color.
How does different light intensities affect the rate of photosynthesis?
As you rise from low light intensity to higher light intensity, the rate of photosynthesis will increase because there is more light available to drive the reactions of photosynthesis. … At a very high intensity of light, the rate of photosynthesis would drop quickly as the light starts to damage the plant.
