The root cap is a section 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] It secretes mucilage to ease the movement of the root through soil,[1] and may also be involved in communication with the soil microbiota.[1]
The root cap is absent in some parasitic plants[2]:138 and some aquatic plants, in which a sac-like structure called the root pocket may form instead.[3]:2-76
