Answer 1

The transverse section of a typical

dicotyledonous root shows following

anatomical features. The outermost single layer

of cells without cuticle is Epiblema. Some of

its cells are prolonged into unicellular root hair.

Next to it is the Cortexwhich consists of several

layers of typical parenchymatous cells. After

the death of epiblema, outer layer of cortex

become cutinized and is called Exodermis.

The cortical cells store food and water. The

innermost layer of cortex is called Endodermis.
