What happens to plants during 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 CO2 compensation point in photosynthesis?

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 …

What is the variation in photosynthesis?

Variations for photosynthesis. Sometimes the conditions for photosynthesis are less than optimal. In warmer regions, plants may lose excessive amounts of water from their leaves by transpiration and need to conserve water. They close their stomates to reduce water loss.

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 is meant by 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 true about CO2 compensation point in C3 and C4 plants?

In C4 plants, the compensation point is lower due to the high affinity of an enzyme PEP-carboxylase. In C3 plants no such reason is there and the compensation point is higher. So, the correct option is A. Compensation point of C3 plants is higher.

What is the meaning of compensation point?

What is natural genetic variation?

‘Genetic variation’ describes the naturally occurring differences in DNA sequences that are found among individuals of the same species. These genetic differences arise from random mutations and may be passed on to their offspring.

Which of the following is an Anoxygenic photosynthetic organism?

3. Which of the following is an anoxygenic photosynthetic organism? Explanation: Green and Purple photosynthetic organism is an anoxygenic photosynthetic organism while rests are oxygenic in nature.

What is the compensation point of photosynthesis?

For instance, in the early morning and late evenings, the compensation point may be reached as photosynthetic activity decreases and respiration increases. Therefore, the partial pressure of CO 2 at the compensation point, also known as gamma, is a function of irradiation.

What is the difference between photosynthesis and assimilation in leaves?

Leaves release CO 2 by photorespiration and cellular respiration, but CO 2 is also converted into carbohydrate by photosynthesis. Assimilation is therefore the difference in the rate of these processes.

What is the relationship between photosynthesis and respiration?

At the compensation point, the rate of photosynthesis is equal to the rate of respiration. Products of photosynthesis are used up in respiration so that the organism is neither consuming nor building biomass.

What is the compensation depth between photosynthesis and respiration of phytoplankton?

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. The compensation point was found nearer to the surface as you move closer to the coast.
