Flashcards on Factors Affecting Photosynthesis
Click on the flashcard to see the answer
What is the effect of increased light intensity on photosynthesis?
Increased light intensity leads to a high rate of photosynthesis.
How does the concentration of CO2 affect photosynthesis?
Higher carbon dioxide concentration increases the rate of photosynthesis.
What is the optimum temperature range for efficient photosynthesis?
An optimum temperature range between 25 to 35oC is required for efficient photosynthesis.
Why is water essential for photosynthesis?
Water is essential for photosynthesis and helps in carbon dioxide intake.
How does a polluted atmosphere affect photosynthesis?
A polluted atmosphere can lead to a decrease in the rate of photosynthesis.
What happens to the rate of photosynthesis in low light intensity?
The rate of photosynthesis decreases in low light intensity.
What is the required carbon dioxide concentration for photosynthesis?
A carbon dioxide concentration of 0.03 to 0.04 percent is sufficient for photosynthesis.
What happens to the stomata when water is scarce?
When water is scarce, the stomata refuse to open to conserve water.
How do pollutants affect photosynthesis?
Pollutants settle on leaves and block the stomata, reducing the rate of photosynthesis.
What is the effect of temperature outside the optimum range on photosynthesis?
Photosynthesis is less efficient outside the temperature range of 25 to 35oC.
What is the effect of low carbon dioxide concentration on photosynthesis?
Low carbon dioxide concentration reduces the rate of photosynthesis.
What happens to the stomata when there is a high concentration of pollutants?
High concentration of pollutants can block the stomata, hindering carbon dioxide intake.
How does light intensity affect the rate of photosynthesis?
Light intensity directly affects the rate of photosynthesis.
What is the effect of temperature on photosynthesis?
Temperature has a significant impact on the efficiency of photosynthesis.
What are the factors required at an optimum level for constant photosynthesis rate?
Factors such as light intensity, carbon dioxide concentration, temperature, and water must be at optimum levels for a constant rate of photosynthesis.
How does a polluted atmosphere impact photosynthesis?
A polluted atmosphere can cause a decrease in the rate of photosynthesis.
