Rhizomes

Rhizomes are thick fleshly underground stem which grows more or less in a horizontal pattern beneath the surface of the soil. Food that is stored in the stem is starch. It has a node and internodes such as ginger corms. This is an underground stem which grows vertically in the soil. The stem is short and swollen with food reserve. Scaled leaved, nods lateral buds are arranged over it while the terminal is at the top.

During favorable season, the terminal bud grows upward to form leaves. Food is then manufactured by the leaves, the new corms has adventitious and contract roots. The contract which is the root helps to hold the corm firmly to the soil, while the adventitious root is used to absorb water from the soil.
