  1. ~A Root Cap is a section of tissue at the tip of a plant root. Root caps contain statoliths which are involved in gravity perception in plants. If the cap is carefully removed the root will grow randomly. The root cap protects the growing tip in plants. It secretes mucilage to ease the movement of the root through soil, and may also be involved in communication with the soil microbiota.

    ~A Root Pocket is a structure that fits over a root tip like a glove finger.  Although root pockets are much more conspicuous than are the root caps of soil roots, their advantage to the plant is less evident.  Toots intermediate between soil and water roots are found in various attached aquatics, such as Elodea and Myriophyllum.  Horizontal branches give rise to hairless unbranched roots resembling water roots, but, as soon as they enter the soil, they branch freely and produce hairs.




  2. 1) Root-cap -  It is the protective covering at the root tip

    It is generated by the apical meristem ( Specially called Calyptrogen . Calyptra means cap .)

    Due to friction with the soil particles the tissue of root cap is continuousely being sloughed off .

    New tissue is constantly produced to take the place of the cells removed .

    So root cap is a constant feature of a root tip that is actively growing .

    Root- caps are found in the terrestrial plants where the roots encounter soil patricle during their growth .

    2 ) Root-pockets - These are basically root caps but have lost there utility due to non use .

    This is because the roots of the plants that hang freely in water have no friction or resistance from the soil particles to overcome .

    So root pockets are vestigeal ( Non functional ) root caps .

    Once removed ; there are not regenerated .

    Found only in floating aquatic plants like Pistia ; Water hyacinth and trapa .

    Click the link for picture -( It is Pistia plant with rootpockets as black streaks at the root tips ) -
