Modification of stems for the storage of food: In some plants, the stem is modified to perform other functions such as storage of food, support, vegetative propagation, and protection. We will learn about each class with modified stem examples in this topic. It bears adventitious roots on its lower side and leaves on upper side. It is special underground stem modification that does not store food materials in stem. Some weak stemmed plants produce wiry, coiled sensitive and delicate organs called tendrils. Primary grade classrooms are rich with opportunities to investigate and explore. In some plants the aerial stem is modified to perform a variety of special functions. They help in propagation through asexual reproduction. The aerial stem modifications causes massive modification of the stem and they are difficult to be recognized as stems.
