Explanation:
Biennial are those crops which takes two years to complete its life cycle i. e. vegetative stage and reproductive stage. First stage is the vegetative stage in which vegetative parts such as roots, stems, leaves and branches are formed. Second stage is reproductive stage in which flowers formed first and after that seeds are produced due to fertilization. Seeds are the babies of plants.
