Such plants live only under rather cool climatic conditions. Examples of other roots which store food are carrot, radish, yam, sweet potato, etc. This food storage in roots is of much practical value to mankind.

The sugar beet has, in Europe especially, become the basis of a great industry. Water Roots. — In the duckweed, a plant living in water, the roots are short and contain few root hairs. The water supply is so great that few root hairs have been called forth. The water hyacinth is another example of slight development of roots. The plant is buoyed up by the water and does not need strong roots to hold it firm. Adventitious Roots. — Roots are often developed in unusual places. Roots coming out thus, as, for example, on the stem, are called adventitious. Such roots are developed along the stem of many climbing plants — for example, the roots of Enghsh ivy. Some plants, as strawberry, couch grass, and many others, develop new.
