What is dark reaction explain briefly?

The first stable product in the C_$3$ plant is Phosphoglyceric acid.

Match the plants in Column I with their features listed in the Column II, III and IV.

Choose the correct combination.

CAM or Crassulacean Acid Metabolism is an alternative pathway of carbon fixation found in hydrophytes.

Assertion (A): ${\mathrm{C}}_4$ plants show greater productivity of biomass than ${\mathrm{C}}_3$ plants.

Reason (R): Leaves of ${\mathrm{C}}_4$ plants have "Kranz anatomy" where bundle sheath cells lack Rubisco enzyme. As a result, ${\mathrm{C}}_4$ plants lack photorespiration.

The correct answer is

One of the following combinations is correct with reference to photosynthesis

Acid concentration in $\mathrm{CAM}$ plants is more at
 

CAM plants are mostly

Which part of the photosynthetic process does not require light and is temperature dependent?

Fixation of CO₂, by crassulacean acid metabolism, is the physiological adaptation in xerophytes and succulent plants. Explain? 

For the same amount of ${\mathrm{CO}}_2$ fixed, a ${\mathrm{C}}_4$ plant in comparison to ${\mathrm{C}}_3$ plant loses only

Which one of the following is an efficient converter of sunlight?

Assertion (A): In C₃ plants photosynthesis is more than C₄ plants.
Reason (R): C₄ plants have a shorter CO₂ fixation cycle.

The acid concentration in CAM plants is more at

The common feature in CAM and ${\mathrm{C}}_4$ plants is________
