Give scientific reasons: Water is essential for germination.

(N/A) $1$. Water brings about the activation of the dormant protoplasm. The activation of cells requires about $75-95 \%$ of water for carrying out their metabolism.
$2$. It is essential for respiration because oxygen reaches the protoplasm only when dissolved in water.
$3$. Water softens the seed coat (testa),causing the seeds to swell. This allows the embryo to break through the softened seed coat and emerge easily.
