If half of the leaves of a plant are removed,the rate of photosynthesis would be

Photosynthetic yield is maximum at the

Which of the following factors affecting photosynthesis does not have a direct effect on the process?
$I$. Light
$II$. Water
$III$. Temperature
$IV$. Carbon Dioxide
Select the correct option.

The Law of Limiting Factors was proposed by .........

The rate of photosynthesis is maximum in the $P$ region of light and minimum in the $Q$ region of light.

Identify the incorrect sentences:
$(I)$ Humidity in the atmosphere is relatively higher in areas where light becomes a limiting factor for plants.
$(II)$ An increase in light intensity beyond a certain point causes the breakdown of chlorophyll,leading to a decrease in the rate of photosynthesis.
$(III)$ $C_4$ plants respond to higher temperatures and show higher rates of photosynthesis,while $C_3$ plants have a much lower temperature optimum.
