(N/A) $(1)$ Differences between Light reaction and Dark reaction:

Light reaction	Dark reaction
$(1)$ Occurs in the grana of the chloroplast.	$(1)$ Occurs in the stroma of the chloroplast.
$(2)$ Light is essential for this phase.	$(2)$ Light is not directly required for this phase.
$(3)$ $O_2$ is released due to the photolysis of water.	$(3)$ $CO_2$ fixation occurs in this phase.
$(4)$ It is the first phase of photosynthesis.	$(4)$ It is the second phase of photosynthesis.
$(5)$ $NADPH$ and $ATP$ are produced.	$(5)$ $NADPH$ and $ATP$ are consumed for the reduction of $PGA$.

$(2)$ Differences between Mesophyll cells and Bundle sheath cells:

Mesophyll cells	Bundle sheath cells
$(1)$ Present in both monocot and dicot leaves.	$(1)$ Present in $C_4$ plants,surrounding the vascular bundles.
$(2)$ Chloroplasts contain well-developed grana.	$(2)$ Chloroplasts are often agranal (lack grana).
$(3)$ Primary $CO_2$ fixation occurs here in $C_4$ plants.	$(3)$ Calvin cycle ($C_3$ cycle) occurs here.
$(4)$ Not typically arranged in a ring around vascular bundles.	$(4)$ Arranged in a ring (Kranz anatomy) around vascular bundles.

Column-$I$	Column-$II$
$(1)$ Cyclic photophosphorylation	$(a)$ Only $PS-I$
$(2)$ Non-cyclic photophosphorylation	$(b)$ $ATP$ formed
$(3)$ $C_4$ cycle	$(c)$ Meristematic tissue
	$(d)$ High productivity

Provide the differences between:
$(1)$ Light reaction (Light phase) and Dark reaction (Biosynthetic phase)
$(2)$ Mesophyll cells and Bundle sheath cells
