Give scientific reasons:
$(1)$ Transpiration is a necessary evil.
$(2)$ Water is life for plants.

(N/A) $(1)$ Transpiration serves multiple essential functions for the plant:
$\Rightarrow$ It plays a crucial role in the ascent of sap by creating a transpiration pull.
$\Rightarrow$ It maintains the turgidity of cells,which is essential for structural support.
$\Rightarrow$ It provides the necessary water for photosynthesis in leaves.
$\Rightarrow$ It provides a cooling effect,thereby maintaining the leaf temperature.
$\Rightarrow$ It facilitates the absorption of mineral salts from the soil and their transport to various parts of the plant.
Because it is essential for these vital processes despite causing significant water loss,it is termed a 'necessary evil'.
$(2)$ Water is fundamental for plant life because:
$\Rightarrow$ It is the primary medium for all physiological processes.
$\Rightarrow$ It is a major component of the protoplasm.
$\Rightarrow$ It directly influences the growth and productivity of plants.
$\Rightarrow$ It acts as a solvent for various hormones,enzymes,mineral salts,and nutrients,facilitating their transport throughout the plant body.
