Question

What are the Function of Monocot root.

Answer 1

The typical monocot roots show the following features:

1). Epiblema is single layered, thin-walled, colourless, polygonal without intercellular spaces, with the presence of unicellular root hairs, hence also called as a piliferous layer or rhizodermis.

2). Cortex may be heterogeneous with outer dead exodermis.

3). Endodermis consists of barrel-shaped parenchyma without intercellular spaces. Casparian stripes are little present but passage cells are absent.

4). Pericycle gives lateral roots only, secondary growth is absent.

5). Vascular bundles are radial; Xylem is exarch, bundles more than six.

6). Metaxylem elements are oval or circular.

7). Conjunctive tissues are limited or even absent.

8). Pith is large or rarely reduced. The roots of monocot perform the same function of conducting water and minerals across plant like any other plant roots.
