Consciousness is a defining property of all living organisms. Whereas coma is profound or deep state of unconsciousness lasting more than six hours, in which person can not be awakened, fails to respond normally to painful stimuli, light or sound. Such person exhibit complete absence of awakefulness and unable to consciously feel, speak, hear or move. Such person is brain dead and we consider such person as living dead.

The similarity and dissimilarity between whole moong daal and broken moong daal is as follows

S.N.	Whole Moong Daal	Broken Moong Daal
1.	Whole moong dal is a intact seed of a plant.	It is not intact seed.
2.	When given all suitable conditions for germination, it germinates.	Unable to germinate as vital seed part such as embryo and cotyledons are destroyed.
3.	During germination, it resumes metabolic activity.	Unable to resume metabolic activity.
4.	Due to metabolism activated enzymes hydrolyse stored food in the cotyledons.	Broken seed will imbibe water, enzyme will get activated but will not lead to growth.
5.	Uses oxygen and respire as a result emits $\mathrm{CO}_2$.	Because of destruction of embryo, no respiration, so no $\mathrm{CO}_2$ emission.
6.	As seed resumes active metabolism the embryo givens rise to plumule (shoot) and radicle (root).	No such growth seen, but broken daal has nurishment value for human as its cotyledons have stored food material rich in protein.

So, we can conclude that broken moong daal does not have viable embryo so does not germinate and does not show any metabolism and growth, but it has great nutritive value as it has good amount of protein and minerals.
