Question

What will be the effect of intermittent light on photosynthesis?
A. It will increase
B. It will decrease
C. Will not be affected
D. Process will stop

Answer 1

Hint: Photosynthesis is the process used by plants to make their own food by using sunlight, carbon dioxide and water. Light is a very important factor in this process. Reduction of photosynthesis occurs in high amounts of light. Consumption of energy currencies occur when the light is interrupted. Production of carbohydrates can be increased by this phenomenon.

Complete answer:
Photosynthesis is the process which occurs in the presence of the light. Light is the important source of energy for the plants. The rate of photosynthesis can be measured by checking the rate of light output, rate of carbon dioxide and also the rate of carbohydrate production. Intermittent light is the type of light which is not steady or continuous. Two types of reactions occur in plants that are: light reaction and dark reaction. Light reactions are faster than dark reactions. Due to this ATP and NADPH accumulate in the plants. Reduction of photosynthesis can occur due to this.
In case there is an interruption of light ATP and NADPH are fully consumed. Reduction of CO2 leads to the formation of glucose.
From the above information we have found that when light is interrupted the rate of photosynthesis increases.

Hence, the correct answer is option (A).

Note: Photosynthesis can be affected by many factors such as light, temperature, pH, amount of CO2 etc. when the intensity of light increases absorption of carbon dioxide by the plants also increases. This can lead to an increase in photosynthesis rate. These are also the limiting factors of photosynthesis.
