The stem is the part of the plant that provides support and helps in conduction.
In some plants, the stem is modified for some other functions such as:
Underground stem modification- in such modification, stems remain under the soil and store the large amount of food e.g., potato, ginger etc.
Sub-aerial modification- in such modification, week stems lie horizontally on the ground and develop adventitious roots that help in vegetative propagation e.g., grass, pumpkin etc.
Aerial stem modification- in such modification, axillary buds are modified to thron and tendril for protection and support e.g., rose, pea etc.
