After growing aerially for some time it bends downwards to touch the ground, where its terminal bud gives rise to a new shoot and adventitious roots. (iii) Internal structure resembles that of aerial stem and not of root. Aerial stem modifications are modifications to the aerial stems, vegetative buds and floral buds of plants growing in different conditions and which perform functions such as climbing, protection, synthesis of food, or vegetative propagation.
