So when this transformed organism will allow growing on the agar containing ampicillin then this transformed organism will easily grow and reproduce on agar containing ampicillin because now it has an ampicillin-resistant gene which will protect it from ampicillin antibiotic. So the transformed cell will grow on agar containing ampicillin.
