In which of the following is light energy stored in the form of chemical energy?

Which of the following factors is essential for photosynthesis?

Assertion: Photosynthetically,$C_4$ plants are less efficient than $C_3$ plants.
Reason: The operation of the $C_4$ pathway requires the involvement of only bundle-sheath cells.

$A-$ In chloroplast,the membrane system is responsible for trapping the light energy and also for the synthesis of $ATP$ and $NADPH$. This is called the light reaction.
$R-$ In the stroma,enzymatic reactions incorporate $CO_2$ into the plant,leading to the synthesis of sugar.

In bacterial photosynthesis,which of the following is present?

Suppose $Euphorbia$ and $Maize$ are grown in a tropical area. Which one of them do you think will be able to survive better under such conditions?
