If the stem grows towards sunlight and the root grows in the opposite direction,the movement of the stem is called:

What is $P$ in the given curve?

Match the following (Condition for growth):

$P$	$Q$
$1.$ Nutrients (Macro and Micro)	$a.$ Medium for enzymatic activities
$2.$ Oxygen	$b.$ Synthesis of protoplasm and act as a source of energy
$3.$ Water	$c.$ Releasing metabolic energy for growth activities
