Hi Shubha ,
Examples in NCERT is mostly given in case of botany parts like in plant kingdom , plant morphology - anatomy , environmental biology etc . In zoology plant kingdom , biotechnology etc have examples . In all cases example given in NCERT is sufficient for NEET . But still study some extra facts from coaching module , it will give you an extra edge in exam . Specifically give attention in coaching module in case of human and plant physiology . All the best .
