The tutor visits the distinction between the similar-sounding structures rhizoid and rhizome.
Rhizoids are simple structures that resemble roots but are are more primitive. They provide anchorage and some absorption of water and nutrients. Fungi and mosses have rhizoids in place of actual roots.
A rhizome is a structure found in a plant that has true roots. Ironically, though found underground, a rhizome is a specialized stem, rather than a root. The potatoes we eat are rhizomes.
