  • Onion consist of both aerial and underground stem.

  • The underground stem is highly reduced into a condensed disc shaped structure called Bulb.

  • The fleshy scale leaves are surrounded by a thin papery outer scale called Tunic that prevents it from drying out. This type of bulb is called Tunicated bulb.
