The Production of Root Hairs by Aquatic Plants

The roots of aquatic plants have received relatively little attention. They are the least known, least understood, and least appreciated parts of aquatic plants. A vivid mental picture of an aquatic plant seldom includes the roots or root hairs. The frequently grossly inaccurate statements regarding the nature and extent of root hairs in aquatic plants have suggested the need of the present study-an intensive survey of the occurrence of root hairs on the roots of aquatic plants. A record of such factual data is a necessary preliminary step before it is possible to evaluate some of the opinions regarding the occurrence and functions of roots of aquatic plants.
