Factors Affecting Photosynthesis
BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337181 Statement A :
Water stress causes the stomata to close hence reducing the \(C{O_2}\) availability
Statement B :
Water stress also makes leaves wilt, thus, reducing the surface area of leaves and their metabolic activity

1 Statement-A is correct but Statement-B is incorrect
2 Statement-A is incorrect but Statement-B is correct
3 Both the statements are correct
4 Both the statements are incorrect
BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337182 What is the impact of closure of stomata on photosynthesis?

1 Increases the \(C{O_2}\) availability
2 Reduces the \(C{O_2}\) availability
3 Increases \({O_2}\) availability
4 Increases temperature directly
BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337183 Assertion :
Water stress is caused by insufficient soil moisture and is among the chief causes of poor growth or poor health in plants
Reason :
There exists for each plant a range of watering, neither too wet nor too dry, within which it is able to grow and maintain good health.

1 Both Assertion and Reason are true and Reason is correct explanation of Assertion.
2 Both Assertion and Reason are true but Reason is not the correct explanation of Assertion.
3 Assertion is true but Reason is false.
4 Both Assertion and Reason are false.
BIOXI13: PHOTOSYNTHESIS IN HIGHER PLANTS

337184 Assertion :
Under conditions of water stress, the rate of photosynthesis declines
Reason :
Stomatal closure and resultant decrease in \(C{O_2}\) supply
