Define the following terms: $Somatic$ $hybridisation$ and $Totipotency$.

(N/A) $Somatic$ $hybridisation$: Isolated protoplasts from two different varieties of plants,each having a desirable character,can be fused to obtain hybrid protoplasts. These can be further grown to form a new plant. These hybrids are called $somatic$ $hybrids$,and the process is known as $somatic$ $hybridisation$.
$Totipotency$: The capacity of any cell or explant to generate a whole plant when grown in a test tube under sterile conditions in special nutrient media is called $totipotency$.
