Solution

The correct option is B
Humid environment

The leaves of certain plants exhibit droplets of water along their margins in the morning. This particularly happens to plants growing in warm humid conditions. A humid environment hampers transpiration while the roots continue to absorb water from the soil. This builds up a big hydrostatic pressure within the plant and forces out the excess water directly from the tips of veins in the leaves.

Q. Assertion :The atmospheric concentration of

C O_{2}

at which photosynthesis just compensates for respiration is referred to as

C O_{2}

compensation point. Reason: The

C O_{2}

compensation point is reached when the amount of

C O_{2}

uptake is less than that generated through respiration, because the level of

C O_{2}

in the atmosphere is more than that required for achieving

C O_{2}

compensation point.

" The rate of photosynthesis increases with increase in intensity of sunlight till 0.02 % CO2 level and further increases with increase in intensity of sunlight only if CO2 level rises to 0.05%, " As per the video lesson and our book . But increase in CO2 level above 0.02% causes stomatal closure, which should reduce the rate of exchange of gases causing decrease in the rate of photosynthesis. Then why it's opposite happens?
