A) Epiblema, cortex, endodermis, pericycle
B) Cortex, epiblema, pericycle, endodermis
C) Epiblema, cortex, pericycle, endodermis
D) Cortex, epiblema, endodermis, epidermis
Correct Answer: A
Solution :
Anatomically root is distinguishable into following layers or regions sequentially : Epiblema \[\to \] Cortex \[\to \] Endodermis \[\to \] Pericycle \[\to \] Vascular system \[\to \] Pith. Epiblema is the outermost piliferous layer of root tissue. Cortex is the extrastelar fundamental tissue of the sporophytes. Endodermis is the most innermost layer of cortex, surrounding the pericycle. Pericycle is the external layer of stele or the layer between endodermis and conducting tissues.
