Along other root segments absorption was similar. Absorbed potassium is transported to the root tip, and to a lesser extent other parts of the root, then also to the shoot and grain. Calcium transport from the apical segment is slower, mostly transported upward and accumulated in stem and shoot. [46]
In morphology, a root is a morphologically simple unit which can be left bare or to which a prefix or a suffix can attach. [2] [3] The root word is the primary lexical unit of a word, and of a word family (this root is then called the base word), which carries aspects of semantic content and cannot be reduced into smaller constituents.
In a vascular plant, the stele is the central part of the root or stem [1] containing the tissues derived from the procambium. These include vascular tissue, in some cases ground tissue and a pericycle, which, if present, defines the outermost boundary of the stele.

Tuberous roots or root tubers – Narrow sense, those storage roots that do not conform to a specific shape, such as fasciculated, nodulose moniliform, annulated, etc.: e.g. sweet potato (Ipomoea batatas), whose edible part is a root of this type. Broader sense, adventitious roots swollen due to their storage function.
Root Cap: Protective layer of cells that covers the meristematic tissue. The cells in this part of the root have been seen to play a critical role in gravitropic response and releasing secretions to mobilize nutrients. The following description is for early events in lateral root formation of the model organism Arabidopsis thaliana:
The English language uses many Greek and Latin roots, stems, and prefixes.These roots are listed alphabetically on three pages: Greek and Latin roots from A to G; Greek and Latin roots from H to O
Fusiform root: this root is widest in the middle and tapers towards the top and the bottom: e.g. radish. Napiform root: the root has a top-like appearance. It is very broad at the top and tapers suddenly like a tail at the bottom: e.g. turnip. The edible, orange part of the carrot is its taproot. Many taproots are modified into storage organs ...
