Important points

• Onion consist of both aerial and underground stem.

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

• The scale leaves arising from the bulb are modified to store food and become fleshy.

• 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.
