Increase in $CO_2$ concentration around the leaf results in:

If the rate of translocation of food is slow,what will be the effect on photosynthesis?

In which of the following are stomata absent?

What happens when the temperature increases above $35^{\circ}C$?

During photosynthesis,what percentage of incident solar radiation is utilized by higher plants?

Assertion : The atmospheric concentration of $CO_2$ at which photosynthesis just compensates for respiration is referred to as $CO_2$ compensation point.
Reason : The $CO_2$ compensation point is reached when the amount of $CO_2$ uptake is less than that generated through respiration because the level of $CO_2$ in the atmosphere is more than that required for achieving $CO_2$ compensation point.
