Select the correct option regarding photosynthesis.

The approximate amount of water on Earth that is split by photosynthesis once every $2$ million years is:

Which of the following is a $CAM$ plant?

Read the following four statements ($a, b, c,$ and $d$) carefully and select the option that includes both correct statements.
$(A)$ The $Z$-scheme of light reaction occurs only in the presence of $PSI$.
$(B)$ Only $PSI$ is functional in cyclic photophosphorylation.
$(C)$ Cyclic photophosphorylation results in the synthesis of $ATP$ and $NADPH_2$.
$(D)$ Stroma lamellae lack both $PS-II$ and $NADP$ reductase $(FNR)$.

$A$ student performed an experiment on photosynthesis as follows: They took soda water in a glass tumbler and added chlorophyll to it. They placed the tumbler in sunlight,expecting that they had provided all the necessary components for photosynthesis (i.e.,$CO_2$,$H_2O$,chlorophyll,and light). What do you think will happen after a few hours of exposure to sunlight?

Match the sites in column $I$ with the processes in column $II$ and choose the correct combination from the options:

Column $I$	Column $II$
$A$. Grana of chloroplast	$1$. Kreb's cycle
$B$. Stroma of chloroplast	$2$. Light reaction
$C$. Cytoplasm	$3$. Dark reaction
$D$. Mitochondrial matrix	$4$. Glycolysis
