Bulbs , corms and Tuber are the specially modified resting stages of sure plants which enable them to live , dormant ( e.g. not actively produce ) , through some adverse climatical status ( ordinarily drought ) . They all contain a entrepot of concentrated food , and dormant buds , some of which in the bulbs and corm may have fertilized egg flush already form inside them , so that when worthy growing condition fall back , the leaves and flowers are produce in a very short time . Because they are not actively growing they can be dig up , transported and sell in shop with small check to the future increase of the flora .
Bulbs contain their food reserve in either peculiar swollen scale - like leaves , loosely packed round the raw bud , as in a lily electric-light bulb ; or in tightly packed foliage bases encircling the bud , as in daffodil , tulip or onion ( genus Allium ) . In the 2nd type the exterior of the electric-light bulb is protected by teetotal , often skin - like , foliage bases . All parts spring from a very flattened stem area known as the ‘ home plate ’ , from the bottom of which the roots farm .
Bulbous plants are phallus of either the lily family or the amaryllis family or of the genusIris .
Corms disagree from medulla in that it is the theme , often flattened , which contains the food for thought reserve . The main bud arises from the center of the upper surface ; other buds may often be seen at the sides . Protective scales are dry . Roots form around the edge of the scar of the previous year ’s corm .
Each bud is adequate to of making a new corm and so small cormels come up around the main corm and spread the plant . The plants producing the corms we are considering all belong to the Iris family line .
The swollen sphere of a genus Tuber may arise from a stem or from both root and shoot , but although a root word tuber will produce root when it starts to grow it is seldom that a root tuber which has lost its shoot ( bud ) will raise another . Tubers may have plate leaves but more usually miss these . genus Tuber are not a method of generation as belittled ones are not formed from them , as in bulbs and corm .
