- A root apical meristem is protectedby a thimble-like root cap. Draw andlabel a simple outline of a root dividedinto four sections: root cap (at thebottom), root apical meristem, primarymeristems, and mature tissues.Discuss the various functions of roots (at least two functions)Which of the following statements are true for root endodermis?I. Endodermal cells constitute the innermost layer of root cortex and surrond the vascular cylinder (xylem and phloem). II. Endodermal wall is covered with waxy layer of casparian strip which blocks apoplastic transfer of minerals.III. Due to presence of casparian strip, water and minerals can only eneter the vascular cylinder if they will be able to cross the plasma membrane of an endodermal cell.
