The root cap is a type of tissue at the tip of a plant root. [1] It is also called calyptra. Root caps contain statocytes which are involved in gravity perception in plants. [1] If the cap is carefully removed the root will grow randomly. The root cap protects the growing tip in plants. [1]
Root mucilage is made of plant-specific polysaccharides or long chains of sugar molecules. [1] [2] This polysaccharide secretion of root exudate forms a gelatinous substance that sticks to the caps of roots. [3] Root mucilage is known to play a role in forming relationships with soil-dwelling life forms.
In flowering plants, the operculum, also known as a calyptra, is the cap-like covering or "lid" of the flower or fruit that detaches at maturity. The operculum is formed by the fusion of sepals and/or petals and is usually shed as a single structure as the flower or fruit matures. [1] The name is also used for the capping tissue of roots, the ...
Root Cap – a cover or cap-like structure that protects the tip of root. Multiple root caps - several layers of root caps on a single root apex; seen in Pandanus sp. Root Pocket – a cap-like structure on the root-apex of some aquatic plants, which, unlike root-caps, doesn't reappear if removed somehow.
An antique spurge plant, Euphorbia antiquorum, sending out white rhizomes In botany and dendrology, a rhizome (/ ˈ r aɪ z oʊ m / RY-zohm) [note 1] is a modified subterranean plant stem that sends out roots and shoots from its nodes.
It harbors two pools of stem cells around an organizing center called the quiescent center (QC) cells and together produces most of the cells in an adult root. [21] [22] At its apex, the root meristem is covered by the root cap, which protects and guides its growth trajectory. Cells are continuously sloughed off the outer surface of the root ...

The root cap of new roots helps the root penetrate the soil. These root caps are sloughed off as the root goes deeper creating a slimy surface that provides lubrication. The apical meristem behind the root cap produces new root cells that elongate. Then, root hairs form that absorb water and mineral nutrients from the soil. [6]
