Choose the correct statement.

Easy

A

Temperature shows more influence on dark reaction of photosynthesis.
B

Temperature does not show any influence on light reaction of photosynthesis.
C

At higher temperatures $C_{3}$ plants show higher rates of photosynthesis than $C_{4}$ plants.
D

The temperature optima for photosynthesis of plants are also dependent on the habit of the plant.

Solution

Temperature has more influence on the dark reaction than light reaction of photosynthesis because complete dark reaction is enzymatic process and the enzymes are temperature sensitive. Light reaction is less affected by temperature than dark reaction. Habit of the plant is nothing to do with influence of temperature on their photosynthesis.
