$(I)$ Chromosome cluster at opposite spindle poles.

$(II)$ Nuclear envelope assembles around the chromosome clusters.

$(III)$ Golgi complex and $ER$ reform.

$I$. $H^{+i i}$ concentration gradient established

$II$. $H^{+i i}$ diffuses through $ATP$ synthetase

$III.$ Carriers use energy from electrons to move $H^{+i i}$ across the membrane

$IV$. Electrons from $PS-II$ pass along electron transport chain

$V.$ Light excites electrons in $PS-II$

$VI.$ Energy of $H^{+i 6}$ flow is used by $ATP$ synthetase to make $ATP$
