Is there any exact definition of vegetable and fruit? How can new plant be classified?
A true fruit is a ripened ovary that usually starts ripening when it is fertilized. And vegetable is any vegetative part of the plant which is edible and contains stored food probably in the form of starch.
Classification is based on several different criteria, for example the mode of reproduction, arrangement and design of flowering parts and flowers and also on the basis of habitat and habit.
