ANATOMY OF DICOT STEM


Dicots, or dicotyledons, are a group of flo
that are characterized by having two se
cotyledons, in their seeds. The anatomy o
is distinct and reflects their ability to
primary and secondary growth. Unlike mo
possess vascular bundles arranged in a ci
around a central pith. These vascular
“open,” meaning they contain a cambium
allows the plant to grow in thicknes
growth). The stem structure of dicots,
defined cortex, pith, and vascular bun
crucial role in supporting the plant an
water, nutrients, and food.
Transfer section of a dicot stem such as su
shows the internal primary structure.
 Epidermis

, It consists of following tissues.
 Hypodermis.
 General cortex .
 Endodermis.
Hypodermis
•It is present just below the epidermis •
layers •Cells are collenchymatous and
chloroplast.
General cortex
•It is present internal to hypodermis •C
walled parenchymatous.
Endodermis
•It is the inner most layer of cortex •ce
or less barrel shape •Cells contain num
grains. •It is also called starch sheath .
Stele
It consists of following parts:-
 Pericycle
 Pith
 Medullary rays
 Vascular bundle
