Frozen vegetables

A while ago we had a discussion in our friends group on frozen stuff. We all were unanimous on prepared frozen food and the vote was a no. 

The votes divided when it came to frozen vegetables, some of us were all fresh and some others were arguing that if they are properly packed then they contain all the nutrients and hence what is the harm?. The discussion ended with Ayurveda says fresh is good. 

After all the time that has passed, couple of days ago I realized that when a fresh vegetable is frozen it is essentially dead. On the other hand when a fruit, vegetable or a green is plucked from the plant, it still has some life which is evident from the veggies ripening after being plucked or the evident fact that greens are able to fight off bacteria and other microbes for a couple of days after being plucked. 

Now my question or dilemma is, how important is for the plant to have some form of life left in it for our consumption? or rather does it make a difference apart from the taste?
